Metabolite Identification
Common NameHeme A
DescriptionHeme a is a derivative of protoheme IX (heme b or heme). Heme a differs from heme b in that a methyl side chain at ring position 8 is oxidized into a formyl group, and one of the vinyl side chains, at ring position 2, has been replaced by an isoprenoid chain. In the heme biosynthesis from uroporphyrinogen-III pathway, different derivatives of protoheme can actually be formed that differ in modifications to the porphyrin ring, including how it is bound to the protein (e.g. heme o, heme a, heme c, and heme d).
