Heme, or haem , is a precursor to hemoglobin, which is necessary to bind oxygen in the bloodstream. Heme is biosynthesized in both the bone marrow and the liver. In biochemical terms, heme is a coordination complex "consisting of an iron ion coordinated to a porphyrin acting as a tetradentate ligand, and to one or two axial ligands." The definition is loose, and many depictions omit the axial ligands. A… WebThe heme prosthetic group in myoglobin and haemoglobin is made up of a protoporporphoryn IX ring (shown in green) and an iron ion in the ferrous (Fe II) oxidation state (shown in silver). This ferrous ion binds four nitrogen atoms within the ring (shown in blue) and will form two additional bonds on either side of the plane of the porphyrin ...
