title: Diurnal variation of rat liver enzymes catalyzing bile acid conjugation and sulfation.
abstract: This study investigated the diurnal variation in the activity of the hepatic enzymes catalyzing conjugation and sulfation of bile acids. A circadian rhythm was noted in cholic acid : CoA ligase and glycolithocholate sulfotransferase activity. There was no diurnal variation in lithocholate sulfotransferase activity raising the possibility of multiple bile acid sulfotransferases in liver.
