L-Cystine(CAT: R056690) is a naturally occurring amino acid formed by the oxidation of two cysteine molecules, making it a dimer of cysteine. Its mode of action involves being a fundamental component in the structure of proteins and an essential part of the body’s antioxidant defense system. Pharmacologically, L-Cystine is not used as a therapeutic drug on its own. Instead, it plays a vital role in various physiological processes, including protein synthesis, cellular repair, and detoxification of harmful substances. L-Cystine is crucial for the formation of disulfide bonds in proteins, contributing to their stability and proper folding.
