Heme iron fe

The heme group is a highly conjugated ring system (which allows its electrons to be very mobile) surrounding an iron ion. The iron in cytochromes usually exists in a ferrous (Fe ) and a ferric (Fe ) state with a ferroxo (Fe ) state found in catalytic intermediates. Cytochromes are, thus, capable of performing electron transfer reactions and catalysis by reduction or oxidation of their heme iron. The cellular location of cytochromes depends on their function. They can be found as globular proteins Webheme Molecular Formula CHFeNO Average mass 616.487 Da Monoisotopic mass 616.177307 Da ChemSpider ID 4802 - Charge - Double-bond stereo More details: …
