D-Cysteine hydrochloride hydrate（Cat No.:I043005）is the hydrochloride salt form of D-cysteine, a stereoisomer of the naturally occurring amino acid cysteine. It is commonly used in research and biochemical studies, especially in protein chemistry, as it contains a thiol group (-SH) that is critical for forming disulfide bonds, which stabilize protein structures. The hydrate form ensures solubility in aqueous solutions. D-Cysteine hydrochloride hydrate is also used in studies related to redox biology, enzyme catalysis, and the synthesis of peptides and small molecules with cysteine residues, as well as in exploring antioxidant properties.
