Porphobilinogen is an intermediate in the biosynthesis of heme

Definition

ChEBI: Porphobilinogen is a dicarboxylic acid that is pyrole bearing aminomethyl, carboxymethyl and 2-carboxyethyl substituents at positions 2, 3 and 4 respectively. It has a role as a metabolite, an Escherichia coli metabolite and a mouse metabolite. It is a member of pyrroles, a dicarboxylic acid and an aralkylamino compound. It is a conjugate acid of a porphobilinogen(1-).

Biochem/physiol Actions

Intermediate in the biosynthesis of heme.

Purification Methods

Porphobilinogen recrystallises as the monohydrate (pink crystals) from dilute NH4 OAc solutions of pH 4, and is dried in vacuo. The hydrochloride monohydrate has m 165-170o(dec) (from dilute HCl).
