L-Cysteine-D-penicillamine Disulfide (CAS 18840-45-4)

L-Cysteine-D-penicillamine Disulfide is a compound that is of particular interest in the study of thiol-disulfide exchange reactions, which are fundamental to understanding redox biology and the regulation of protein function. This disulfide compound is used in research to model the oxidation of thiol-containing proteins and peptides, as well as to investigate the mechanisms of reducing agents within biological systems. The disulfide bond in L-Cysteine-D-penicillamine Disulfide can be selectively reduced to free thiols, making it useful in the study of enzymatic and non-enzymatic processes that modulate the thiol-disulfide status of cellular proteins. In addition, this compound is utilized in the preparation of chiral stationary phases for enantioselective chromatography, exploiting the stereospecific interactions that can occur due to the presence of both L- and D-configured amino acids. Research involving L-Cysteine-D-penicillamine Disulfide also extends to the field of materials science, where it can be employed in the design of novel metal-binding polymers or as a crosslinker in the synthesis of hydrogels with tunable mechanical properties.
