Bilirubin (CAS NO.635-65-4) is also called Hematoidin;bilirubin (ex pig) ; 21H-Biline-8,12-dipropanoic acid,2,17-diethenyl-1,10,19,22,23,24-hexahydro-3,7,13,18-tetramethyl-1,19-dioxo- ; 2,17-Diethenyl-1,10,19,22,23,24-hexahydro-3,7,13,18-tetramethyl-1,19-dioxo-21H-biline-8,12-dipropanoic acid ; 13,18-Tetramethyl-1,19-dioxo- ; 1,10,19,22,23,24-hexahydro-2,7,13,17-tetramethyl-biline-12-dipropionicacid . Bilirubin (CAS NO.635-65-4) is soluble in benzene, chloroform and carbon disulfide and other organic solvents; also soluble in hot ethanol and chloroform mixture; salt soluble in water, but calcium, magnesium and barium salts do not dissolve in water. Bilirubin is created by the activity of biliverdin reductase on biliverdin. Bilirubin, when oxidized, reverts to become biliverdin once again. This cycle, in addition to the demonstration of the potent antioxidant activity of bilirubin, has led to the hypothesis that bilirubin's main physiologic role is as a cellular antioxidant. |
