Abstract

An abnormal series of porphyrin tetracarboxylic acids known as the isocoproporphyrins, are commonly excreted by patients suffering from the disease porphyria cutanea tarda (PCT). These porphyrins appear to arise by bacterial degradation of dehydroisocoproporphyrinogen that is generated by the premature metabolism of the normal pentacarboxylate intermediate (5dab) by coproporphyrinogen oxidase (copro'gen ...
