Chemically, hemin differs from the related heme-compound hematin chiefly in that the coordinating ion is a chloride ion in hemin, whereas the coordinating ion is a hydroxide ion in hematin. The iron ion in haem is ferrous (Fe ), whereas it is ferric (Fe ) in both hemin and hematin. Hemin is endogenously produced in the human body, for example during the turnover of old red …
WebJan 5, 1995 · Iron can be added to protoporphyrin IX. The oxidation state of the iron ion and the identity of the negatively charged counterion determine the name of the product. If iron (II), or ferrous iron, is added the product is heme. If iron (III), or ferric iron, is added the product is. hemin if the counterion is chloride.
