Cysteine

Description:

Cysteine is a naturally occurring amino acid that plays a crucial role in protein synthesis and various metabolic processes. It is classified as a non-essential amino acid, meaning the body can synthesize it from other compounds. Cysteine contains a thiol (-SH) group, which is responsible for its unique properties, including its ability to form disulfide bonds with other cysteine residues, contributing to the stability and structure of proteins. This amino acid is also involved in the synthesis of glutathione, a vital antioxidant that protects cells from oxidative stress. Cysteine is soluble in water and has a polar side chain, making it hydrophilic. It can exist in different forms, including L-cysteine, which is the biologically active form. Additionally, cysteine can participate in various biochemical reactions, including those related to detoxification and metabolism. Its presence in dietary sources such as meat, eggs, and dairy products underscores its importance in human nutrition and health.
