Protoporphyrin IX reacts with iron salts in air to give the complex FeCl(PPIX). Heme coordinated with chlorine is known as hemin. Many metals other than Fe form Heme-like complexes when coordinated to PPIX. Of particular interest are cobalt derivatives because they also function as oxygen carriers.
Definition. Heme, the ferrous iron complex of protoporphyrin IX, is a common prosthetic group in proteins including the electron transfer cytochromes, the respiratory complexes, and the oxygen carrier hemoglobin. Basic Characteristics. Introduction.
