Description

D-Selenocystine CAS NO 26932-45-6 is the D-isomer of the selenium-containing amino acid derivative, selenocystine, where two D-selenocysteine molecules are linked via a diselenide bridge. This compound is a crucial chiral building block and biochemical tool for studying selenium's role in biological systems, particularly in the synthesis of selenoproteins and as a precursor for selenocysteine. It is primarily utilized by research institutions, pharmaceutical developers, and biotechnology companies engaged in redox biology, enzyme mechanism studies, and the development of novel therapeutic agents and diagnostic tools.

Application

• Biochemical Research: Essential reagent for investigating the biochemistry of selenium, selenoprotein synthesis, and redox signaling pathways.
• Pharmaceutical Intermediates: Serves as a chiral precursor in the synthesis of potential therapeutic compounds targeting oxidative stress and related disorders.
• Nutritional Science Studies: Used in research to understand the metabolic pathways and bioavailability of organic selenium compounds.
• Enzyme Mechanism Probes: Acts as a substrate or inhibitor in enzymatic studies, particularly for selenoenzymes like glutathione peroxidase.
• Reference Standard: Employed as a high-purity analytical standard in HPLC, LC-MS, and other chromatographic methods for quality control and method validation.
• Cell Culture & In Vitro Studies: Used in media supplementation to study the effects of specific selenium species on cell growth, function, and response to oxidative damage.
