cysteinylcysteine

Description:

Cysteinylcysteine, also known as cysteine-cysteine or cysteine disulfide, is a dipeptide formed from two cysteine amino acids linked by a disulfide bond. It is characterized by the presence of a thiol (-SH) group in each cysteine residue, which plays a crucial role in protein structure and function. The disulfide bond formed between the thiol groups contributes to the stabilization of protein tertiary and quaternary structures, influencing the overall conformation and activity of proteins. Cysteinylcysteine is soluble in water and exhibits a relatively low molecular weight. It is involved in various biological processes, including redox reactions and the regulation of cellular signaling pathways. Additionally, it can act as an antioxidant, protecting cells from oxidative stress. The compound is of interest in biochemistry and pharmacology, particularly in the study of protein folding and stability, as well as in the development of therapeutic agents targeting redox-sensitive pathways. Its CAS number, 18048-87-8, is used for identification in chemical databases and regulatory contexts.
