Chemical compound
Taurocholic acid , known also as cholaic acid , cholyltaurine , or acidum cholatauricum , is a deliquescent yellowish crystalline bile acid involved in the emulsification of fats . It occurs as a sodium salt in the bile of mammals . It is a conjugate of cholic acid with taurine . In medical use, it is administered as a cholagogue and choleretic .[ 1]
Hydrolysis of taurocholic acid yields taurine .
For commercial use, taurocholic acid is manufactured from cattle bile, a byproduct of the meat-processing industry.[ 2]
This acid is also one of the many molecules in the body that has cholesterol as its precursor.[citation needed ]
Toxicity
The median lethal dose of taurocholic acid in newborn rats is 380 mg/kg.[citation needed ]
