D-Cysteine hydrochloride（Cat No.:I043157）is the hydrochloride salt of D-cysteine, an isomer of the naturally occurring amino acid cysteine. This compound contains a thiol group (-SH), which plays a crucial role in redox reactions, protein folding, and the formation of disulfide bonds that stabilize protein structures. D-Cysteine hydrochloride is often used in biochemical research, particularly in studies of protein structure, enzyme catalysis, and redox processes. It is also used in the synthesis of peptides and small molecules where cysteine residues are important. The hydrochloride form enhances its solubility in aqueous solutions for laboratory applications.
