Metabolite Identification
Common Name(4E,15Z)-Bilirubin
Description(4E,15Z)-Bilirubin IXa belongs to the class of organic compounds known as bilirubins. These are organic compounds containing a dicarboxylic acyclic tetrapyrrole derivative. Bilirubin (BR) is a yellow compound that occurs in the normal catabolic pathway that breaks down heme in vertebrates. (4E,15Z)-Bilirubin IXa is a linear tetrapyrrole, and a product of heme degradation. It is a member of the class of compounds known as biladienes. Biladienes consist of two linear tetrapyrroles in which the carbon bridges contain two more double bonds than bilane. (4E,15Z)-Bilirubin IXa is an isomer of bilirubin, which appears to have antioxidant effects. Bilirubin's antioxidant activity may be particularly important in the brain, where it prevents excitotoxicity and neuronal death by scavenging superoxide during N-methyl-D-aspartic acid neurotransmission. (4E,15Z)-Bilirubin IXa is formed by oxidative cleavage of a porphyrin in heme, which first produces biliverdin. Biliverdin is then reduced to bilirubin by biliverdin reductase. Some of the double-bonds in bilirubin isomerize when exposed to light. The E,Z-isomers of bilirubin, such s (4E,15Z)-Bilirubin IXa formed upon light exposure are more soluble than the unilluminated Z,Z-isomer. Altered levels of (4E,15Z)-Bilirubin IXa in human serum have been used as a biomarker of acrylamide exposure (PMID: 28163100 ).
