The urine anion gap is calculated using measured ions found in the urine. It is used to aid in the differential diagnosis of metabolic acidosis. The term "anion gap" without qualification usually implies serum anion gap. The "urine anion gap" is a different measure, principally used to determine whether the kidneys are capable of appropriately acidifying urine.

In 1927 Erling Johnson developed an industrial method for producing nitrophosphate, also known as the Odda process after his Odda Smelteverk of Norway.

Therefore acydophobes would prefer pH above 7. Acid intolerance of plants may be mitigated by lime addition and by calcium and nitrogen fertilizers. Acidophobic species are used as a natural instrument of monitoring the degree of acidifying contamination of soil and watercourses. For example, when monitoring vegetation, a decrease of acidophobic species would be indicative of acid rain increase in the area.

For example, an experimental study on hornblende granite in New Jersey, USA, demonstrated a 3x – 4x increase in weathering rate under lichen covered surfaces compared to recently exposed bare rock surfaces. Biological weathering of basalt by lichen, La Palma. The most common forms of biological weathering are the release of chelating compounds (i.e. organic acids, siderophores) and of acidifying molecules (i.e.

Emmental cheese, the as-yet-undrained curd is broken by rotating mixers. A required step in cheesemaking is separating the milk into solid curds and liquid whey. Usually this is done by acidifying (souring) the milk and adding rennet. The acidification can be accomplished directly by the addition of an acid, such as vinegar, in a few cases (paneer, queso fresco).

Intermediate-strength hydrochloric acid solutions are quite stable upon storage, maintaining their concentrations over time. These attributes, plus the fact that it is available as a pure reagent, make hydrochloric acid an excellent acidifying reagent. Hydrochloric acid is the preferred acid in titration for determining the amount of bases. Strong acid titrants give more precise results due to a more distinct endpoint.

The gallbladder is an excretory organ that is pear-shaped and identified between two liver lobes. It is divided into three sections a body, neck and fundus. The main function of this excretory organ is storing, acidifying and concentrating bile. This is achieved due to the nature of the muscular sac being a thin wall that can easily distend to accommodate the bile.

In 1970, Feiden exhibited the photographs of Joel-Peter Witkin. Witkin photographed Feiden, and a Witkin photograph became the basis of one of Hirschfeld's portraits of Feiden. Also in 1969, Feiden began working on the restoration of documents and works of art on paper, removing adhesives, de-acidifying the paper, and reweaving damaged paper fibres. Feiden's gallery specializes in American art of the 20th century.

Proton pumping pyrophosphatase (also referred to as H-PPase or vacuolar-type inorganic pyrophosphatases (V-PPase; V is for vacuolar)) is a proton pump driven by the hydrolysis of inorganic pyrophosphate (PPi). In plants, H-PPase is localized to the vacuolar membrane (the tonoplast). This membrane of plants contains two different proton pumps for acidifying the interior of the vacuole, the V-PPase and the V-ATPase.

Contribution of Working Group I to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change. (15MB) and raising levels of carbon dioxide in the atmosphere. These rising levels of carbon dioxide are acidifying the oceans.

Acacia has a strong tendency to spread and produces chemical substances that suppresses the growth of native plants, which are then replaced by nitrophilous types, such as stinging nettle (Urtica dioica), which degrades the area. Furthermore, knotweed (Reynoutria) occurs there and spreads rapidly, displacing native species and acidifying the soil. It is removed several times a year using glyphosate herbicides. In the caves, bioluminescence is produced in place of permanent lighting.

This reaction causes the pH of the water to lower, effectively acidifying it. Ocean acidification is occurring in every ocean across the world. Since the beginning of the Industrial Revolution, the World's oceans have absorbed approximately 525 billion tons of carbon dioxide. During this time, world ocean pH has collectively decreased from 8.2 to 8.1, with climatic modeling predicting a further decrease of pH by 0.3 units by 2100.

Sclerotia and the asexual conidia spores contribute to the widespread infection of the pathogen. A low pH is preferred by the gray mold to perform well. Botrytis cinerea can acidify its environment by secreting organic acids, like oxalic acid. By acidifying its surroundings, cell wall degrading enzymes (CWDEs) are enhanced, plant-protection enzymes are inhibited, stomatal closure is deregulated, and pH signaling is mediated to facilitate its pathogenesis.

Sulfur and nitrogen, as acidifying agents, may change soil nutrient content by removing calcium and releasing toxic aluminum, further impacting plants and animals.Driscoll, C. T., G. B. Lawrence, A. J. Bulger, T. J. Butler, C. S. Cronan, C. Eagar, K. F. Lambert, G. E. Likens, J. L. Stoddard, and K. C. Weathers. 2001. Acidic Deposition in the Northeastern United States: Sources and Inputs, Ecosystem Effects, and Management Strategies.

Unfortunately, the contaminated groundwater that needs to be treated has a pH level that is at or near neutral. Due to this, there are controversies on whether ISCO using Fenton's reagent is really a Fenton reaction. Instead, scientists call these reactions Fenton-like. However, some ISCO vendors successfully apply pH neutral Fenton's reagent by chelating the iron which keeps the iron in solution and mitigates the need for acidifying the treatment zone.

To relieve tumors cells of acidosis, carbonic anhydrases appear to be highly expressed once again downstream of HIF-1 activation. These enzymes catalyze the reversible hydration of carbon dioxide into bicarbonate and protons. They also assist in acidifying the extracellular environment and maintaining a slightly alkaline intracellular compartments contributing to tumor cell survival. Lactate from the hypoxic tumor cells is excreted to the surrounding environment by carbonic anhydrase 9 and sodium-hydrogen exchanger 1 MCT4.

Frémy therefore devised a method for producing dry hydrogen fluoride by acidifying potassium bifluoride (KHF2). Unfortunately, pure hydrogen fluoride did not pass an electric current. Frémy also tried electrolyzing molten calcium fluoride and probably produced some fluorine (since he made calcium metal at the other electrode), but he was unable to collect the gas. English chemist George Gore also tried electrolyzing dry HF and may have made small quantities of fluorine gas in 1860.

These unparalleled marine and coastal living resources provide profound benefits to the 363 million people who reside within the six countries that compose the Coral Triangle, along with benefits to many millions more outside the region. Today, the coastal and marine ecosystems in the Coral Triangle are under significant and increasing threat by the warming, acidifying and rising seas. Coral reefs have experienced mass bleaching, which threaten to degrade the important ecosystems.

DL-Methionine is sometimes given as a supplement to dogs; It helps reduce the chances of kidney stones in dogs. Methionine is also known to increase the urinary excretion of quinidine by acidifying the urine. Aminoglycoside antibiotics used to treat urinary tract infections work best in alkaline conditions, and urinary acidification from using methionine can reduce its effectiveness. If a dog is on a diet that acidifies the urine, methionine should not be used.

Similarly, all gaseous molecules emitted and received by plants such as plant hormones and other pheromones must pass the apoplast. In nitrate poor soils, acidification of the apoplast increases cell wall extensibility and root growth rate. This is believed to be caused by a decrease in nitrate uptake (due to deficit in the soil medium) and supplanted with an increase in chloride uptake. H+ATPase increases the efflux of H+, thus acidifying the apoplast.

DCA has been shown to occur in nature in at least one seaweed, Asparagopsis taxiformis. It is a trace product of the chlorination of drinking water and is produced by the metabolism of various chlorine-containing drugs or chemicals. DCA is typically prepared by the reduction of trichloroacetic acid (TCA). DCA is prepared from chloral hydrate also by the reaction with calcium carbonate and sodium cyanide in water followed by acidifying with hydrochloric acid.

Produced in Aegean Region provinces like İzmir, Aydın, Manisa, Muğla and Balıkesir, it is made of raw milk heated to , and cooled immediately down to acidifying temperature. Curds are brined in 16-percentage solution and cured for one night. The curd is filled then in cans with 12-percentage solution of brine for ripening. ;Tulum cheese of Divle Divle is a village in the Ayrancı district of Karaman Province in Central Anatolia Region.

The accelerated burning of fossil fuels within the past century has largely contributed to the acidification of freshwater ecosystems. In the 1970s, the sulfate emissions levels peaked, with nitrogen following behind 10 years later. The main contributors to freshwater acidification are SOx and NOx. Increases in sulfate concentration in runoff, due to increased acidity inputs, is coupled with an increase in base cation run-off and bicarbonate decrease, creating the acidifying effect seen in freshwater ecosystems.

Galectin-8 has also been used to study endosomal disruption in the development of nanoscale drug delivery systems. Many drug delivery systems carrying large molecule drugs, such as antisense oligonucleotides, siRNA, peptides, and therapeutic proteins, are engineered to be pH-responsive, and disrupt the endosomal membrane because of the lower pH found within progressively acidifying endosomes. Galectin-8 can be tagged with a fluorophore to track these disrupted endosomal membranes, especially when coupled with automated microscopy.

The Centers for Disease Control and Prevention (CDC) suggest the same dose for prevention of 125 mg acetazolamide every 12 hours. Acetazolamide, a mild diuretic, works by stimulating the kidneys to secrete more bicarbonate in the urine, thereby acidifying the blood. This change in pH stimulates the respiratory center to increase the depth and frequency of respiration, thus speeding the natural acclimatization process. An undesirable side-effect of acetazolamide is a reduction in aerobic endurance performance.

In June 1990, Dahmer lured a 27-year-old acquaintance named Edward Smith to his apartment. He drugged and strangled Smith. On this occasion, rather than immediately acidifying the skeleton or repeating previous processes of bleaching (which had rendered previous victims' skulls brittle), Dahmer placed Smith's skeleton in his freezer for several months in the hope it would not retain moisture. Freezing the skeleton did not remove moisture, and the skeleton of this victim would be acidified several months later.

Prior to the actual brewing of the liquor, another small batch of grain is prepared to produce the "seed mash" (, jiǔmǔ). Seed mash is produced by soaking and acidifying glutinous rice and other grains, then steaming them on frames or screens for several minutes. This cooks the grains and converts their starch into a gelatinized form that is more easily utilized by the starter culture. The inoculation temperature of the steamed grains is tightly controlled as it alters the flavor character.

They are an intermediate step in the oxidation of ammonia to nitrite, which occurs in the nitrogen cycle. Hyponitrite can act as a bridging or chelating bidentate ligand.Greenwood and Earnshaw, pp. 459–72 Nitrous acid (HNO2) is not known as a pure compound, but is a common component in gaseous equilibria and is an important aqueous reagent: its aqueous solutions may be made from acidifying cool aqueous nitrite (, bent) solutions, although already at room temperature disproportionation to nitrate and nitric oxide is significant.

The excess carbon sequestered by the ocean results in ocean acidification, which has an especially large impact on the Southern Ocean since this ocean basin naturally has lower calcium carbonate concentrations. The increasing acidity will decrease the calcium carbonate concentrations even more making it difficult for calcifying organisms to develop and survive. The decline of calcifying organisms will have serious repercussions for the rest of the food web in the Southern Ocean, so it is important to quantify how much this ocean is acidifying.

In a paper published in 1931, Polyakov reported the effects of presence of different solvents (benzene, toluene and xylene) on the silica pore structure during drying a newly prepared silica. When H2SO4 was used as the polymerization initiator (acidifying agent), a positive correlation was found between surface areas, e.g. load capacities, and the molecular weights of the respective solvents. Later on, in 1949 Dickey reported the polymerization of sodium silicate in the presence of four different dyes (namely methyl, ethyl, n-propyl and n-butyl orange).

With his money almost gone and his second daughter born, he took a contract with the government of Guatemala as a bacteriologist at the General Hospital in Guatemala City. Some of his work included organizing defenses against the dread diseases of the time: malaria and yellow fever. He also studied a local fungal infection of coffee plants, and discovered that acidifying the soil could serve as an effective treatment. As a side job, he was asked to find a way to make whiskey from bananas.

Film by Psihoyos that broadcasts and educates viewers on the horrific events damaging our planet's health and wildlife. All of these In the documentary the tragic slaughtering of sea life all around the world is brought to viewers attention. Racing Extinction addresses two major causes of species extinction: climate change and the wildlife trade. Marine species are featured prominently for both, from tiny organisms whose shells are dissolving as a result of acidifying ocean water, to large whale sharks caught for their fins, meat and oil.

Continuous Drip irrigation would lead to alkali soils formation in the absence of leaching / drainage water from the field. It is also possible to reclaim alkaline soils by adding acidifying minerals like pyrite or cheaper alum or Aluminium sulfate. Alternatively, gypsum (calcium sulfate, CaSO4.2H2O) can also be applied as a source of Ca++ ions to replace the sodium at the exchange complex. Gypsum also reacts with sodium carbonate to convert into sodium sulphate which is a neutral salt and does not contribute to high pH.

It has a secondary laxative effect in the colon, where it is fermented by the gut flora, producing metabolites which have osmotic powers and peristalsis- stimulating effects (such as acetate), but also methane associated with flatulence. Lactulose is metabolized in the colon by bacterial flora to short- chain fatty acids, including lactic acid and acetic acid. These partially dissociate, acidifying the colonic contents (increasing the H+ concentration in the gut). This favors the formation of the nonabsorbable from NH3, trapping NH3 in the colon and effectively reducing plasma NH3 concentrations.

This stage is characterised by the body employing physiological mechanisms, including neural, hormonal and bio-chemical mechanisms, in an attempt to reverse the condition. As a result of the acidosis, the person will begin to hyperventilate in order to rid the body of carbon dioxide (CO2). CO2 indirectly acts to acidify the blood, so the body attempts to return to acid–base homeostasis by removing that acidifying agent. The baroreceptors in the arteries detect the hypotension resulting from large amounts of blood being redirected to distant tissues, and cause the release of epinephrine and norepinephrine.

It is thought that the low pH of hypoxic tumors in result of high levels of lactic acid can promote tumor cell invasion by destruction of adjacent non-cancerous tissue.> Carbonic anhydrase 9 involved in maintaining a slightly alkaline intracellular pH does so by removing carbonate from the extracellular space consequently acidifying the cells surroundings. Moreover, proton pumping from the hypoxic tumor cells further decreases the surrounding pH. On a completely different note, as briefly discussed above, the autocrine function of phosphoglucose isomerase also promotes cell motility and metastasis.

HA17 and HA18 have been described to bind MHC class II molecules as a receptor for entry rather than sialic acid. The host cell membrane then engulfs the virus, a process known as endocytosis, and pinches off to form a new membrane-bound compartment within the cell called an endosome. The cell then attempts to begin digesting the contents of the endosome by acidifying its interior and transforming it into a lysosome. Once the pH within the endosome drops to about 5.0 to 6.0, a series of conformational rearrangement occurs to the protein.

Commercial feline foods limit the amount of magnesium and add acidifiers such as DL-Methionine to increase urine acidity, thereby reducing the likelihood of struvite formation (alternatively, adding Vitamin C has a similar acidifying effect). However, whilst acidic urine is associated with a decrease in struvite uroliths, excessive acidity can result in an increase in calcium oxalate uroliths, low magnesium levels and urine pH both being factors in calcium oxalate formation. Oxalate uroliths are not dissolvable in cat urine. Less common forms of uroliths include ammonium urate, uric acid, calcium phosphate, and cystine uroliths.

Attachment to the bone matrix is facilitated by integrin receptors, such as αvβ3, via the specific amino acid motif Arg-Gly-Asp in bone matrix proteins, such as osteopontin. The osteoclast releases hydrogen ions through the action of carbonic anhydrase (H2O + CO2 → HCO3− \+ H+) through the ruffled border into the resorptive cavity, acidifying and aiding dissolution of the mineralized bone matrix into Ca2+, H3PO4, H2CO3, water and other substances. Dysfunction of the carbonic anhydrase has been documented to cause some forms of osteopetrosis. Hydrogen ions are pumped against a high concentration gradient by proton pumps, specifically a unique vacuolar-ATPase.

P. cubensis) The active ingredient in psychedelic mushrooms is psilocybin, while the active ingredients in medicinal mushrooms are thought to be beta-glucans. The extraction process involved in creating mushroom tea is variable, but typically involve repeatedly soaking the mushrooms in less-than boiling water and straining the fungal matter afterwards. By extracting the components of the fungal matter into the boiling water, residual psilocybin can be accumulated and stored for later use. Many variations exist in creating mushroom tea, including simple straining, using teabags, using coffee makers, adding vitamin C, and slightly acidifying the water (ex: with lemon juice).

If the pH is over seven then consider soil remediation that will lower the pH toward the 6.5 - 7 range. Remediation includes: i) adding compost, manure, peat or similar organic matter (warning. Some retail blends of manure and compost have pH in the range 7 - 8 because of added lime. Read the MSDS if available.) ii) applying Ammonium Sulphate as a Nitrogen fertilizer (acidifying fertilizer due to decomposition of ammonium ion to nitrate in the soil and root zone) iii) applying elemental Sulphur to the soil (oxidizes over the course of months to produce sulphate/sulphite and lower pH).

The nitrophosphate process (also known as the Odda process) was a method for the industrial production of nitrogen fertilizers invented by Erling Johnson in the municipality of Odda, Norway around 1927. The process involves acidifying phosphate rock with nitric acid to produce a mixture of phosphoric acid and calcium nitrate. :Ca3(PO4)2 \+ 6 HNO3 \+ 12 H2O -> 2 H3PO4 \+ 3 Ca(NO3)2 \+ 12 H2O The mixture is cooled to below 0 °C, where the calcium nitrate crystallizes and can be separated from the phosphoric acid. :2 H3PO4 \+ 3 Ca(NO3)2 \+ 12 H2O -> 2 H3PO4 \+ 3 Ca(NO3)2·4H2O The resulting calcium nitrate produces nitrogen fertilizer.

The Norwegian name for Rumex lapponicus, setersyre, has led to some speculation that it was used on Mid-Norwegian summer farms as an acidifying agent. The United States Department of Agriculture has listed Rumex lapponicus as a noxious weed in the state of Arkansas, indicating that members of the genus Rumex "can directly or indirectly injure or cause damage to crops (including nursery stock or plant products), livestock, poultry or other interests of agriculture, irrigation, navigation, the natural resources of the United States, the public health, or the environment", in an official profile on the USDA website, and thus subject to interstate travel restrictions within the US.

Soil acidification is a common issue in long-term crop production which can be reduced by lime application. In soybean and corn crops grown in acidic soils, lime application resulted in nutrient restoration, increase in soil pH, increase in root biomass, and better plant health. Different management strategies may also be applied to prevent further acidification: using less acidifying fertilizers, considering fertilizer amount and application timing to reduce nitrate-nitrogen leaching, good irrigation management with acid-neutralizing water, and considering the ratio of basic nutrients to nitrogen in harvested crops. Sulfur fertilizers should only be used in responsive crops, with a high rate of crop recovery.

While ongoing ocean acidification is at least partially anthropogenic in origin, it has occurred previously in Earth's history, and the resulting ecological collapse in the oceans had long-lasting effects for global carbon cycling and climate. The most notable example is the Paleocene-Eocene Thermal Maximum (PETM), which occurred approximately 56 million years ago when massive amounts of carbon entered the ocean and atmosphere, and led to the dissolution of carbonate sediments in all ocean basins. Ocean acidification has been compared to anthropogenic climate change and called the "evil twin of global warming" and "the other problem". Freshwater bodies also appear to be acidifying, although this is a more complex and less obvious phenomenon.

297x297px Freshwater becomes acidic when acid inputs surpass the quantity of bases produced in the reservoir through weathering of rocks, or by the reduction of acid anions, like sulfate and nitrate within the lake. The main reason for freshwater acidification is atmospheric depositions and soil leaching of SOx and NOx. In an acid-sensitive ecosystem, which includes slow- weathering bedrock and depleted base cation pools, SOx and NOx from runoff will be accompanied by acidifying hydrogen ions and inorganic aluminum, which can be toxic to marine organisms. Acid rain is also a contributor to freshwater acidification, however acid rain is formed when SOx and NOx react with water, oxygen and oxidants within the clouds.

This image shows a bowl of white rice with mold growing over it. Fungi have been seen as a method of food spoilage, causing only an undesirable appearance to food, however, there has been significant evidence of various fungi being a cause of death of many people spanning across hundreds of years in many places through the world. Fungi are caused by acidifying, fermenting, discoloring and disintegrating processes and can create fuzz, powder and slimes of many different colors, including black, white, red, brown and green. Mold is a type of fungus, but the two terms are not reciprocal of each other; they have their own defining features and perform their own tasks.

Animal protein has a high acidic amino acid content (glutamic and aspartic acid); therefore, its nitrogenous metabolites that are excreted via the urine are acidic, making the normal range of a dog's urine pH 5–7. Plant-based protein is relatively lower in these acidifying amino acids, which can lead to urinary alkalization (pH > 7). Alkaline urine puts dogs at an increased risk of developing struvite crystals, dysuria, hematuria and obstructing the urinary tract, which can have fatal outcomes. Vitamin C, potassium chloride, DL-methionine, and cranberry (which promotes overall health of the urinary tract), as well as peas, brown rice, and lentils all promote GI health and urine acidification, and can be used to correct the alkalinity of urine.

In the prevention or treatment of mountain sickness, acetazolamide forces the kidneys to excrete bicarbonate, the conjugate base of carbonic acid. Increasing the amount of bicarbonate excreted in the urine causes the blood to become more acidic. As the body equates acidity of the blood to its CO2 concentration, artificially acidifying the blood fools the body into thinking it has an excess of CO2, and it excretes this perceived excess CO2 by deeper and faster breathing, which in turn increases the amount of oxygen in the blood. Acetazolamide is not an immediate cure for acute mountain sickness; rather, speeds up (or, when taking before traveling, forces the body to early start) part of the acclimatization process which in turn helps to relieve symptoms.

Adjuvants are chemicals added to enhance the performance/efficacy and/ or alter the physical properties of the pesticidal agents. More than 200 EPA registered pesticides recommends specific addition of one or more adjuvants into the pesticidal mixture to improve overall efficacy. Recognized as "other ingredients", the EPA also establishes tolerance levels for adjuvants, but they are not required to be registered. Examples of adjuvants include: #acidifying agents, #buffering agents, #anti- foam agents, #defoaming agents, #anti-transpirants, #dyes and brighteners, #compatibility agents, #crop oil concentrates, #oil surfactants, #deposition agents, #drift reduction agents, #foam markers, #feeding stimulants, #herbicide safeners, #spreaders, extenders, #adhesive agents, #suspension agents, #gelling agents, #synergists, #wetting agents, #emulsifiers, #dispersing agents, #penetrants, #tank and equipment cleaners, #neutralizers, #water absorbents, and #water softeners.

In 1986, when preparing for a conference to celebrate the 100th anniversary of the discovery of fluorine, Karl O. Christe discovered a purely chemical preparation of fluorine gas; however, he stated in his work that the basics were known 50 years before the actual reaction. The main idea is that some metal fluoride anions do not have a neutral counterpart (or those are very unstable) and their acidifying would result in chemical oxidation, rather than formation of the expected molecules. Christe lists the following reactions as a possible way: :2 KMnO4 \+ 2 KF + 10 HF + 3 H2O2 → 2 K2MnF6 \+ 8 H2O + 3 O2↑ :2 K2MnF6 \+ 4 SbF5 → 4 KSbF6 \+ 2 MnF3 \+ F2↑ This synthetic route is a rare chemical preparation of elemental fluorine, a reaction not previously thought possible.

"Acid rain" is a popular term referring to the deposition of a mixture from wet (rain, snow, sleet, fog, cloudwater, and dew) and dry (acidifying particles and gases) acidic components. Distilled water, once carbon dioxide is removed, has a neutral pH of 7. Liquids with a pH less than 7 are acidic, and those with a pH greater than 7 are alkaline. "Clean" or unpolluted rain has an acidic pH, but usually no lower than 5.7, because carbon dioxide and water in the air react together to form carbonic acid, a weak acid according to the following reaction: : (l) + (g) (aq) Carbonic acid then can ionize in water forming low concentrations of carbonate and hydronium ions: : (l) + (aq) − (aq) + + (aq) Unpolluted rain can also contain other chemicals which affect its pH (acidity level).

To get an idea of the eco-efficiency of Flemish agriculture we compare pressure indicators to an economic indicator. In the period 2007-2012 the final production remains more or less stable, while the environmental indicators evolve. As to the emission of very fine particles, the phosphorus fertilizer use and the pressure by chemical pesticides, the eco-efficiency improves thanks to the manure policy, rising fertilizer prices and the switch to natural gas in horticulture. In contrast, the increasing livestock from 2008 and the increasing number of cogeneration plants (combined heat and power) in greenhouses are the main reasons that there is no decrease in energy consumption, greenhouse gas emissions and potential acidifying emissions. In 2012, the net primary energy use by the agricultural sector amounts to 24 916 TJ. Greenhouse horticulture remains with 46% the largest energy user.

The receptor is then recycled to the apical membrane, while ligand is transported to the late endosome and lysosome where it is degraded. ClC-5 supports efficient acidification of endosomes either by providing a Cl− conductance to counterbalance the accumulation of positively charged H+ pumped in by V-ATPase or by directly acidifying endosome in parallel with V-ATPase. Experimental evidence indicates that endosomal Cl− concentration, which is raised by ClC-5 in exchange for protons accumulated by the V-ATPase, may play a role in endocytosis independently from endosomal acidification, thus pointing to another possible mechanism by which ClC-5 dysfunction may impair endocytosis. ClC-5 is located also at the cell surface of PTCs where probably it plays a role in the formation/function of the endocytic complex that also involves megalin and cubilin/amnionless receptors, the sodium-hydrogen antiporter 3 (NHE3), and the V-ATPase.
