ChEBI Name bilirubin IXα
ChEBI ASCII Name bilirubin IXalpha
Definition A member of the class of biladienes that is a linear tetrapyrrole with the dipyrrole units being of both exovinyl and endovinyl type. A product of heme degradation, it is produced in the reticuloendothelial system by the reduction of biliverdin and transported to the liver as a complex with serum albumin.
