WebMetabolic pathway for bilirubin in the hepatocyte. Bilirubin-G corresponds to bilirubin glucuronate, where the donor is uridine diphosphate glucuronic acid (UDP-GA). This is catalyzed by the enzyme uridine diphosphate-glucuronyltransferase (UGT1A1). Gilbert and Crigler-Najjar syndrome are associated with decreases in UGT1A1 activity.
