The heme molecule acts as prosthetic group for both myoglobin and hemoglobin. The porphyrin ring is present in heme molecule. The iron molecule especially Fe2+ is present in heme molecule. The deoxyhemoglbin states occur when the central atom is displaced 0.4 Å. The iron central atom can form six bonds and forms four bonds with the prophyrin of nitrogen and one bond with histidine molecule. Histidine acts as a buffer fir the blood.
