What is TAUROCHOLIC ACID?

Chemical properties

Crystals. Stable in air. Freely soluble in water; soluble in alcohol, almost insoluble in ether and ethyl acetate.

The Uses of TAUROCHOLIC ACID

Taurocholic Acid is a choleretic steroid useful for the quantification of conjugated bile acids.

The Uses of TAUROCHOLIC ACID

anti-inflammatory

Background

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 solubilize fats for absorption and is itself absorbed. It is used as a cholagogue and cholerectic.

What are the applications of Application

Taurocholic Acid is a choleretic steroid useful for the quantification of conjugated bile acids

Definition

ChEBI: A bile acid taurine conjugate of cholic acid that usually occurs as the sodium salt of bile in mammals.

Metabolism

Not Available

Purification Methods

Crystallise the acid from EtOH/EtOAc/Et2O (amorphous m 125o) or EtOH/Et2O [Josephson Biochem J 29 1484 1935]. The sodium salt (hydrate) [312693-83-7, 345909-26-4 (xH2O)] crystallises from aqueous EtOH/Et2O with m 231-232o, [] D 23 +25.2o (c 1, H2O); and has max (H2SO4) at 303, 389 and 480nm.
