Description

Application

Sodium taurocholate hydrate was used as an emulsifier in in situ preparation of digestive enzymes.

Biochem/physiol Actions

Taurocholic acid 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. These are reabsorbed by the liver via a carrier-mediated process and converted by liver enzymes to taurocholic acid.

Preparation Note

Sodium taurocholate hydrate yields a clear, colorless solution in water at 50 mg/ml.

Other Notes

For the solubilization of unconjugated bilirubin
