Biochem/physiol Actions

Bilirubin is reported to cross the blood-brain barrier and exert significant antioxidant effects in the brain. This pigment aids in coloration in the various forms of jaundice. Bilirubin levels act as biomarkers in liver and blood disorders. Unconjugated form of bilirubin at lower levels serves as a physiological antioxidant. However, increased concentration of bilirubin is toxic and leads to neonatal hyperbilirubinemia in neonates.

General description

Bilirubin is an orange-yellow bile pigment and one of the major end products of hemoglobin decomposition. It contains conjugated double bonds and reactive hydrogen atoms. In adults, the upper limit of the normal range of bilirubin is >1mg/dL. Serum levels of bilirubin in healthy newborns are less than 15 mg/dl. This product corresponds to the unconjugated form.
