Description

Seleno-Dl-Cystine is a selenium-containing derivative of the amino acid cystine, where sulfur atoms are replaced with selenium. This modification is critical for its role as a key precursor and research compound in the study of selenoproteins and selenium's biological functions. It is primarily utilized by researchers and manufacturers in the pharmaceutical, nutraceutical, and life science sectors for developing novel therapeutics and studying antioxidant mechanisms.

Application

• Biochemical Research: A vital standard and intermediate for studying selenium metabolism, selenoprotein synthesis, and redox biology.
• Pharmaceutical Development: Serves as a key building block in the research and synthesis of potential therapeutic agents targeting oxidative stress and related disorders.
• Nutraceutical & Dietary Supplement Research: Investigated for its role as a source of organic selenium in advanced supplement formulations.
• Reference Standard: Used as a high-purity analytical standard in HPLC, LC-MS, and other chromatographic methods for quality control and method validation.
• Enzymology Studies: Employed in research on enzymes that utilize selenocysteine, such as glutathione peroxidase and thioredoxin reductase.
• Cell Culture & In Vitro Studies: Applied in media supplementation to investigate the effects of selenium-amino acid complexes on cell growth and function.
