| cholaic acid | <chemical> 2-(((3 alpha, 5 beta,7 alpha,12 alpha)-3,7,12-trihydroxy-24-oxocholan-24-yl)amino)ethanesulfonic acid. The product of conjugation of cholic acid with taurine. Its sodium salt is the chief ingredient of the bile of carnivorous animals. It acts as a detergent to solubilise fats for absorption and is itself absorbed. It is used as a cholagogue and cholerectic. Pharmacological action: cholagogues and choleretics. Chemical name: Ethanesulfonic acid, 2-(((3alpha,5beta,7alpha,12alpha)-3,7,12-trihydroxy-24-oxocholan-24-yl)amino)- (12 Dec 1998) |
| cholalic acid | A family of steroids comprising the bile acids (or salts), generally in conjugated form (e.g., glycocholic and taurocholic acids). Chemically, cholic acids are cholan-24-oic (cholanic) acids (the terminal C24 of cholane becoming a -COOH group); biologically, cholic acids are derived from cholesterol (a cholestane derivative) and display varying degrees of oxidation (OH groups) and orientation at positions 3, 7, and 12. It is these oxidations and orientations that distinguish the several cholic acid; e.g., cholic acid is 3a,7a,12a-trihydroxy-5b-cholan-24-oic acid, deoxycholic acid is 3a,12a-dihydroxy-5b-cholanic acid. Synonym: cholalic acid, cholanic acid. (05 Mar 2000) |
