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. WebViews. Liver function tests, often known as liver chemistries, measure the levels of proteins, liver enzymes, and bilirubin in your blood to assist in evaluating evaluation of the health of your liver. They can also track the progression or treatment of existing diseases. Depending on the test, higher or lower-than-normal levels of these ...

Infants with refractory seizures may have a serum concentration of phenobarbital of 100 µg/ml. Phenobarbital is metabolized in the liver by CYP2C9 with minor metabolism by CYP2C19 and CYP2E1. WebHeme oxygenase-1 (HO-1) metabolizes heme to generate carbon monoxide (CO), biliverdin, and iron. Biliverdin is subsequently metabolized to bilirubin by biliverdin reductase.

WebBiliary Excretion. Biliary excretion involves active secretion of drug molecules or their metabolites from hepatocytes into the bile. The bile then transports the drugs to the gut, where the drugs are excreted. The transport process is similar to those described for renal tubular secretion. The efficiency of biliary excretion is quite variable. WebNormal bilirubin metabolism can be summarized as a series of steps, including (1) production, (2) uptake by the hepatocyte, (3) conjugation, (4) excretion into bile ducts, and (5) delivery to the intestine.
