Web24-norlithocholic acid (41%). In this study, for the first time, a bile acid diglucuronide, substituted both at 3- hydroxyl and carboxyl groups, was detected (11%). Principal Ca4 bile acids (BA), exemplified by cholic, chenodeoxycholic and deoxycholic acids, are efficiently conjugated with amino acids before their biliary secre- tion. WebBiliary secretion of bile acid glucuronides was studied in control rats and in rats with a congenital defect in hepatobiliary transport of organic anions (GY rats). In control animals, hepatobiliary transport of [3H]lithocholic acid 3-O-glucuronide and [3H]cholic acid 3-O-glucuronide was efficient (greater than 95% in 1 h) and comparable to that of …
