D-Methionine Sulfoxide Hydrochloride(CAT: I046013) is an oxidized derivative of the sulfur-containing amino acid D-methionine, formed through sulfoxidation of the thioether group. This compound is widely used as a biochemical probe to study protein oxidation, redox regulation, and methionine metabolism. It serves as a reference standard in investigating the enzymatic repair of oxidized methionine residues by methionine sulfoxide reductases (MsrA/MsrB), which play essential roles in cellular antioxidant defense and protein homeostasis. With applications in oxidative stress, neurodegeneration, and aging research, D-Methionine Sulfoxide Hydrochloride is a valuable tool for exploring redox biology, protein chemistry, and disease-related oxidative pathways.
