Cholic Acid

Cholic acid is a primary bile acid. It is formed from cholesterol via a multistep process catalyzed by the cytochrome P450 (CYP) isoforms CYP7A1, CYP8B1, and CYP27A1. Cholic acid is conjugated to glycine or taurine by bile acid-CoA:amino acid N-acyltransferase (BAAT) to produce glycocholic acid (GCA, Cay-20276) and taurocholic acid (TCA, Cay-16215), respectively, in the liver, and is transformed into the secondary bile acid deoxycholic acid (DCA, Cay-20756) by intestinal microbiota. It induces C. difficile colony formation in an agar dilution assay when used at a concentration of 0.1% w/v. Dietary administration of cholic acid (0.4% w/w) increases serum cholesterol levels, biliary phospholipid secretion, and fecal DCA levels in rats.Formal Name: (5beta)-3alpha,7alpha,12alpha-trihydroxy-cholan-24-oic acid.
