Bilirubin

Bilirubin is a major component of heme decomposition and the main pigment of bile. It has the functions of an antioxidant and an effective scavenger of hydrogen peroxide radicals, protecting cell membrane lipids from the oxidation of these active radicals. It is generally used in biochemical research, analytical chemistry and synthetic bezoar. It can also be used as an antioxidant to protect membrane phospholipids from oxidation by hydrogen peroxide free radicals, and can protect neurons from oxidative damage even at nanomolar concentrations. It is also used for the determination of artificial bezoar bilirubin.
