Hemoglobin ionic bonds
WebSpecifically, Pauling and Coryell stated that each heme has four unpaired electrons. Thus, they determined that the iron in hemoglobin forms ionic (not covalent) bonds with nitrogen and the globin, while oxyhemoglobin and carbonmonoxyhemoglobin form covalent bonds at the same locations.
