Web13 jan. 2024 · Heme Metabolism. Heme is an iron-containing porphyrin (which is made of 4 pyrrole groups), synthesized mostly in the bone marrow and the liver. Heme is a component of many crucial substances, including cytochromes, myoglobin, and hemoglobin. Biologic functions include the transportation of gases (e.g., O 2 ), and electron transfer. Heme, or haem , is a precursor to hemoglobin, which is necessary to bind oxygen in the bloodstream. Heme is biosynthesized in both the bone marrow and the liver. In biochemical terms, heme is a coordination complex "consisting of an iron ion coordinated to a porphyrin acting as a tetradentate ligand, … Meer weergeven Hemoproteins have diverse biological functions including the transportation of diatomic gases, chemical catalysis, diatomic gas detection, and electron transfer.
