IUPAC 名称
3-(2-{[3-(2-carboxyethyl)-5-[(3-ethenyl-4-methyl-5-oxo-2,5-dihydro-1H-pyrrol-2-ylidene)methyl]-4-methyl-1H-pyrrol-2-yl]methylidene}-5-[(3-ethenyl-4-methyl-2-oxo-2H-pyrrol-5-yl)methylidene]-4-methyl-2,5-dihydro-1H-pyrrol-3-yl)propanoic acid
描述
Biliverdin is a green pigment formed as a byproduct of hemoglobin breakdown. It consists of four linearly connected pyrrole rings (a tetrapyrrole). Biliverdin is formed when the heme group in hemoglobin is cleaved at its alpha-methene bridge. The resulting biliverdin is then reduced to bilirubin, a yellow pigment, by the enzyme biliverdin reductase. The changing color of a bruise from deep purple to yellow over time is a graphical indicator of this reaction. Biosynthesized from hemoglobin as a precursor of bilirubin. Occurs in the bile of amphibia and of birds, but not in normal human bile or serum. [HMDB]
