Heme A
C49H56FeN4O6 (852.3549026000001)
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chain at ring position 8 is oxidized into a formyl group, and one of the vinyl side chains, at ring position 2, has been replaced by an isoprenoid chain. Like heme B, heme A is often attached to the apoprotein (cytochromes or globins) through a coordination bond between the heme iron and a conserved amino acid side-chain. An example of a metalloprotein that contains heme A is cytochrome c oxidase. Both the formyl group and the isoprenoid side chain are thought to play important roles in conservation of the energy of oxygen reduction by cytochrome c oxidase.(Wikipedia).
