IUPAC 名称
3-[(2Z)-2-{[3-(2-carboxyethyl)-5-[(3-ethyl-5-hydroxy-4-methyl-2H-pyrrol-2-yl)methyl]-4-methyl-1H-pyrrol-2-yl]methylidene}-5-[(4-ethyl-5-hydroxy-3-methyl-2H-pyrrol-2-yl)methyl]-4-methyl-2H-pyrrol-3-yl]propanoic acid
描述
Urobilin is one of the final by-products of hemoglobin breakdown. Urobilin is excreted in both the urine and feces from many mammals, particularly humans. The breakdown of hemoglobin to biliverdin is common to most animals, while the next step, the conversion of biliverdin to bilirubin, and subsequently to the urobilinogens (urobilin is one particular oxidized chemical form of urobilinogen) is unique to mammals.
