| | PORPHOBILINOGEN Usage And Synthesis |
| Uses | An intermediate in the biosynthesis of Heme, found in the urine of patients with acute porphyria. | | 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. | | IC 50 | Human Endogenous Metabolite | | 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).
