[PDF] Core Concepts: Bilirubin Metabolism
Bilirubin is formed in the reticuloendothelial system as the end product of heme catabolism through a series of oxidation-reduction reactions. The predominant bilirubin isomer in humans is IX-alpha (Z,Z), which, because of its lipophilic nature, can cross phospholipid membranes. In fetal life, this characteristic permits passage of bilirubin through the placenta into the maternal organism for

This overview is focused on the bilirubin molecule and its important biological properties. For a long time, bilirubin has been considered a waste product of heme catabolism with potential toxic effects especially on the central nervous system. However, bilirubin has attracted the attention of scientists because of its protective effects. Mildly elevated plasma bilirubin levels are associated

Disorders of Bilirubin Metabolism
This chapter provides a brief summary of bilirubin metabolism and its inherited disorders, with emphasis on some significant developments. Serum bilirubin levels were found to be inversely related to the risk of obesity and metabolic syndrome and ischemic coronary artery disease in middle‐aged men.

Bilirubin Metabolism and Hyperbilirubinemia
Acquired causes of hyperbilirubinemia, which usually indicate liver disease or biliary obstruction, need to be differentiated from inborn errors of bilirubin metabolism. In acute hepatitis, jaundice is common and usually transient, whereas in alcoholic hepatitis and alcoholic or nonalcoholic liver cirrhosis, jaundice has a dismal prognosis (1) .

Bilirubin As discussed with normal metabolism, bilirubin is a product of heme breakdown. It exists in conjugated (water soluble) and unconjugated (lipid soluble) forms, which are reported imprecisely as the direct and indirect fractions, respectively. Serum bilirubin
