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 II is a rare isomer.

Porphyrins are compounds containing a fundamental skeleton of four pyrrole nuclei united through the alpha-positions by four methine groups to form a macrocyclic structure.
