taurocholic acid

Taurocholic acid (N-Choloyltaurine) is a bile acid involved in the emulsification of fats.Taurocholic acid is cytoprotective, preventing tumor necrosis factor-alpha-induced cholangiocyte damage via a PI3K-mediated pathway.

Taurocholic acid sodium salt hydrate (Sodium taurocholate hydrate), formed by the conjugation of taurine with cholic acid, is the primary ingredient in the bile of carnivorous animals. It acts as a detergent to solubilize fats for absorption and is employed as a cholagogue and choleretic.

Sodium taurocholate (Taurocholate Sodium) hydrate is the main end product of cholesterol catabolism. During enterohepatic circulation, bile taurocholic acid is converted by the microorganisms to taurodeoxycholic acid and deoxycholic acid.[3] These are reabsorbed by the liver via a carrier-mediated process and converted by liver enzymes to taurocholic acid.

Isodeoxycholic Acid is a bile acid that is formed via epimerization of deoxycholic acid by intestinal bacteria. It has a greater critical micelle concentration than DCA, indicating reduced detergent activity, and is less active than DCA in inhibiting growth in a panel of seven gut commensal bacteria species. Isodeoxycholic Acid(0.1%) inhibits spore germination induced by taurocholic acid in several C. difficile strains, as well as decreases the cytotoxicity of C. difficile culture supernatants to Vero cells. Plasma levels of isodeoxycholic acid are decreased in a rat model of high-fat diet-induced obesity compared with rats fed a normal diet.
