Oxidation state of fe2+

WebAug 27, 2016 · In fact the special physical form of this molecule which is ferrous (Fe2+) allow it to transfer oxygen molecules. When an oxygen molecule binds to hemoglobin it temporarily transfers to the ferric form (Fe3+). So when a hemoglobin oxidizes to the ferric form there will be no place for oxygen to bond with.
