A pigmented protein (or metelloprotein) that contains iron in the form of heme located in red blood cells of vertebrates and responsible for the delivery of oxygen (about 98% of the total) to tissues (heme being the deep red, non-protein, ferrous component of hemoglobin). The color of blood, which varies from bright red when oxygenated to dark red when it is deoxygenated,is due to hemoglobin. <\/p>\n
