Heme (American English) or haem (British English) is a cofactor consisting of an Fe 2+ (ferrous) ion contained in the centre of a large heterocyclic organic ring called a porphyrin, made up of four pyrrolic groups joined together by methine bridges.n peroxidase reactions, the porphyrin molecule also serves as an electron source. In the transportation or detection of diatomic gases, the gas binds to the heme ion. During the detection of diatomic gases, the binding of the gas ligand to the heme ion induces conformational changes in the surrounding protein.
