S-Butyl-D-cysteine

Description:
S-Butyl-D-cysteine, with the CAS number 4134-56-9, is a naturally occurring amino acid derivative characterized by the presence of a sulfur-containing thiol group, which is typical of cysteine. This compound features a butyl side chain attached to the sulfur atom, distinguishing it from other cysteine derivatives. S-Butyl-D-cysteine is known for its potential biological activities, including antioxidant properties and its role in protein synthesis. The presence of the thiol group allows it to participate in redox reactions, making it significant in various biochemical processes. Additionally, the stereochemistry indicated by the "D" prefix suggests that it is the D-enantiomer of cysteine, which can have different biological effects compared to its L-counterpart. This compound may be utilized in research settings, particularly in studies related to protein structure and function, as well as in the synthesis of peptides and other bioactive molecules. Its solubility in water and stability under physiological conditions further enhance its utility in biochemical applications.
