2-hydroxy-3-sulfanylpropanoic acid

Description:

2-Hydroxy-3-sulfanylpropanoic acid, commonly known as cysteine, is a naturally occurring amino acid that plays a crucial role in protein synthesis and various metabolic processes. It contains a thiol (-SH) group, which imparts unique properties, including the ability to form disulfide bonds that stabilize protein structures. This compound is characterized by its polar nature due to the hydroxyl (-OH) and thiol groups, making it soluble in water. Cysteine is also a precursor to the antioxidant glutathione, contributing to cellular defense against oxidative stress. Its structure includes a central carbon atom bonded to an amino group (-NH2), a carboxyl group (-COOH), a hydroxyl group, and a sulfhydryl group. Cysteine is classified as a semi-essential amino acid, meaning that while the body can synthesize it, dietary sources are important, especially under certain physiological conditions. It is found in high-protein foods such as meat, eggs, and dairy products. Additionally, cysteine is involved in various biochemical pathways, including detoxification and the synthesis of other important biomolecules.
