Descriptor uroporfirinógenos
Entry term(s) uroporfirinógeno III
Scope note: Porfirinógenos que son intermediarios en la biosíntesis del heme. Tienen cuatro cadenas laterales de ácido acético y cuatro de ácido propiónico unidas a los anillos pirrólicos. Los uroporfirinógenos I y III se forman a partir del polipirril metano en presencia de uroporfirinógeno III cosintetasa y de uroporfirina I sintetasa, respectivamente. Pueden dar lugar a uroporfirinas mediante autooxidación o a coproporfirinógenos por descarboxilación.

Scope note: Porphyrinogens which are intermediates in heme biosynthesis. 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.
