Homocystine

Description:
Homocystine is a sulfur-containing amino acid that is a dimer of homocysteine, formed when two homocysteine molecules are linked by a disulfide bond. It is classified as a non-proteinogenic amino acid and is involved in various metabolic processes, particularly in the metabolism of sulfur-containing amino acids. Homocystine is typically found in the body in small amounts and is associated with the metabolism of methionine. Elevated levels of homocystine in the blood can be indicative of certain health conditions, including cardiovascular diseases and homocystinuria, a genetic disorder that affects the metabolism of homocysteine. The compound is soluble in water and has a relatively high melting point. Its structure includes a central carbon atom bonded to an amino group, a carboxyl group, and a side chain that contains a thiol group, which is responsible for its reactivity. Homocystine's role in biological systems and its potential implications in health make it a subject of interest in both clinical and biochemical research.
