Iron fe2+
WebDietary iron occurs in three major forms: ferrous iron (Fe2+), ferric iron (Fe3+), and heme iron (Fe 2+ chelated into a complex organic compound to complete the heme structure, which occurs in hemoglobin, myoglobin, and certain enzymes). 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.
