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.

WebBilirubin glucuronides are actively transported into the bile canaliculi by the ATP-utilizing pump MRP2. Bilirubin is degraded in the intestine by bacteria into urobilinogens, which are partly excreted in the urine. Increased production, reduced uptake and low glucuronida-tion capacity can increase plasma unconjugated bilirubin levels. city block indianapolis
