描述
Uroporphyrin is the porphyrin produced by oxidation of the methylene bridges in uroporphyrinogen. They have four acetic acid and four propionic acid side chains attached to the pyrrole rings. Uroporphyrinogen I and III are formed from polypyrryl methane in the presence of uroporphyrinogen III cosynthetase and uroporphyrin I synthetase, respectively. They can yield uroporphyrins by autooxidation or coproporphyrinogens by decarboxylation.
Excessive amounts of uroporphyrin I are excreted in congenital erythropoietic porphyria, and both types I and III are excreted in porphyria cutanea tarda.
Uroporphyrin I and III are the most common isomemrs. Uroporphyrin IV is a rare isomer; Formed together with the other Uroporphyrin isomers by the nonenzymic acid-catalysed polymerisation and oxidn. of Porphobilinogen (Combined Chemical Dictionary) [HMDB]
