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