Heme

Description:

Heme is a complex organic molecule that plays a crucial role in various biological processes, primarily as a prosthetic group in hemoproteins such as hemoglobin and myoglobin. It consists of an iron ion contained within a porphyrin ring, which is a cyclic structure made up of four pyrrole subunits linked by methine bridges. The iron in heme can exist in different oxidation states, allowing it to participate in redox reactions and bind to oxygen, carbon monoxide, and other small molecules. Heme is essential for oxygen transport and storage in living organisms, as well as for electron transfer in cellular respiration. Its structure allows for the reversible binding of oxygen, making it vital for aerobic metabolism. Additionally, heme is involved in various enzymatic reactions, including those catalyzed by cytochromes, which are important for drug metabolism and detoxification processes. The CAS number 14875-96-8 specifically identifies heme, highlighting its significance in biochemistry and medicine.

HEME

CAS: 14875-96-8

Heme is an iron-containing, non-protein molecule that is essential for life. Heme has a variety of biochemical properties and is important in the regulation of vital biological processes such as oxygen transport and metabolism of nitrogenous compounds. Heme can be found in two forms: heme A and heme B. The former consists of the protein globin combined with ferrous ion, while the latter is formed by the combination of protoporphyrin IX with ferrous ion. The synthesis of heme occurs through a series of reactions that involve oxidation and reduction reactions. The protoheme synthesis pathway results in the production of erythrocruorin, which is then converted to hemes A or B depending on its position in the globin protein chain. In addition to being an important cofactor for enzymes such as cytochrome c oxidase (complex IV), heme also functions as a substrate for heme oxygenase, which removes it from circulation to produce biliver
