Dehydrocholic Acid

	Dehydrocholic Acid Dehydrocholic acid is a synthetic bile acid, manufactured by the oxidation of cholic acid Cholic acid, also known as 3α,7α,12α-trihydroxy-5β-cholan-24-oic acid is a primary bile acid that is insoluble in water (soluble in alcohol and acetic acid), it is a white crystalline substance. Salts of cholic acid are called cholates. Cho .... It acts as a hydrocholeretic, increasing bile output to clear increased bile acid load.

picture info	Bile Acid Bile acids are steroid acids found predominantly in the bile of mammals and other vertebrates. Diverse bile acids are synthesized in the liver in peroxisomes. Bile acids are conjugated with taurine or glycine residues to give anions called bile salts. Primary bile acids are those synthesized by the liver. Secondary bile acids result from bacterial actions in the colon. In humans, taurocholic acid and glycocholic acid (derivatives of cholic acid) and taurochenodeoxycholic acid and glycochenodeoxycholic acid (derivatives of chenodeoxycholic acid) are the major bile salts. The salts of their 7-alpha-dehydroxylated derivatives, deoxycholic acid and lithocholic acid, are also found, with derivatives of cholic, chenodeoxycholic and deoxycholic acids accounting for over 90% of human biliary bile acids. Description Bile acids comprise about 80% of the organic compounds in bile (others are phospholipids and cholesterol). An increased secretion of bile acids produces an increase ...

picture info	Redox Redox ( , , reduction–oxidation or oxidation–reduction) is a type of chemical reaction in which the oxidation states of the reactants change. Oxidation is the loss of electrons or an increase in the oxidation state, while reduction is the gain of electrons or a decrease in the oxidation state. The oxidation and reduction processes occur simultaneously in the chemical reaction. There are two classes of redox reactions: * Electron transfer, Electron-transfer – Only one (usually) electron flows from the atom, ion, or molecule being oxidized to the atom, ion, or molecule that is reduced. This type of redox reaction is often discussed in terms of redox couples and electrode potentials. * Atom transfer – An atom transfers from one Substrate (chemistry), substrate to another. For example, in the rusting of iron, the oxidation state of iron atoms increases as the iron converts to an oxide, and simultaneously, the oxidation state of oxygen decreases as it accepts electrons r ...

	Cholic Acid Cholic acid, also known as 3α,7α,12α-trihydroxy-5β-cholan-24-oic acid is a primary bile acid that is insoluble in water (soluble in alcohol and acetic acid), it is a white crystalline substance. Salts of cholic acid are called cholates. Cholic acid, along with chenodeoxycholic acid, is one of the two major bile acids produced by the liver, where it is synthesized from cholesterol. These two major bile acids are roughly equal in concentration in humans. Derivatives are made from cholyl-CoA, which exchanges its CoA with either glycine, or taurine, yielding glycocholic and taurocholic acid, respectively. Cholic acid downregulates cholesterol-7-α-hydroxylase (rate-limiting step in bile acid synthesis), and cholesterol does the opposite. This is why chenodeoxycholic acid, and not cholic acid, can be used to treat gallstones (because decreasing bile acid synthesis would supersaturate the stones even more). Cholic acid and chenodeoxycholic acid are the most important huma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Hydrocholeretic Hydrocholeretics are substances that increase the volume of secretion of bile from the liver without increasing the amount of solids secreted. Some substances can result in decreased solid production, possibly due to circulatory effects. Cyclobutyrol is a compound commonly used as a hydrocholeretic. Its effects in rats include a dose-dependent increase in bile flow, sodium, potassium, chloride and bicarbonate outputs and reduced bile acid concentrations. See also * Cholekinetic * Choleretic Choleretics are substances that increase the volume of secretion of bile from the liver as well as the amount of solids secreted. By stimulating the production of bile, the body is better able to release toxins and through acting as a natural laxa ... References Bile acids {{gastrointestinal-drug-stub ...

	Cholanes Cholane is a triterpene which can exist as either of two stereoisomers, 5α-cholane and 5β-cholane. Its name is derived from (chole) meaning 'bile' in reference to its original discovery from the bile of the American bullfrog (''Rana catesbeiana''). The compound itself has no known uses. However, various functionalized analogues are produced by plants and animals, typically in the form of sterols, steroids and bile acids (e.g. cholic acid).
