Background:
Cholic acid-d4is intended for use as an internal standard for the quantification of cholic acid by GC- or LC-MS. Cholic acid is a primary bile acid.1It is formed from cholesterolviaa 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 and taurocholic acid , respectively, in the liver, and is transformed into the secondary bile acid deoxycholic acid by intestinal microbiota.1,2,3It inducesC. difficilecolony formation in an agar dilution assay when used at a concentration of 0.1% w/v.4Dietary administration of cholic acid (0.4% w/w) increases serum cholesterol levels, biliary phospholipid secretion, and fecal DCA levels in rats.5
