Bile acids labeled with 3H on the sterol nucleus lose a substantial fraction of label during enterohepatic cycling and conversion to secondary bile acids. We tested the isotopic stability of a side-chain 3H label, [22,23-3H]cholic acid in humans. The

The biliary bile acid composition of 30 species of pigeons and doves belonging to seven genera in the avian order Columbiformes was determined using TLC, HPLC, GLC/MS, LSIMS, and NMR. In 23 of 25 species of fruit pigeons and doves, chenodeoxycholic a

The biliary bile acid composition of the adult and neonatal domestic rabbit, as well as that of the adult brush rabbit, was characterized. In adult domestic rabbits, the dominant bile acid present was deoxycholic acid (88% of to- tal bile acids), a s
