Coproporphyrinogens

From Wikipedia, the free encyclopedia

Coproporphyrinogens are tetrapyrroles with four propionic acid groups and an equal number of substituted methyls.

In the metabolism of porphyrin, the enzyme uroporphyrinogen III decarboxylase generates "coproporphyrinogen III" from uroporphyrinogen III, and coproporphyrinogen III oxidase converts it into protoporphyrinogen IX.
