Description

n-Acetyl-L-Selenomethionin is a specialized organoselenium derivative of the essential amino acid methionine, where the selenium atom replaces sulfur. This compound is of significant interest in biochemical research and pharmaceutical development due to its role as a precursor for the targeted incorporation of selenium into proteins and peptides. It is primarily utilized by researchers in life sciences, pharmaceutical R&D, and nutraceutical development for studying selenoprotein synthesis, antioxidant mechanisms, and as a potential source of bioavailable selenium.

Application

• Biochemical Research: Used as a key reagent in the study of selenoprotein biosynthesis and selenium metabolism pathways.
• Pharmaceutical Development: Serves as a precursor for synthesizing selenium-containing peptide analogs and potential therapeutic agents.
• Nutritional Science: Investigated as a source of bioavailable selenium in specialized nutraceutical and dietary supplement formulations.
• Proteomics & Labeling: Employed for the selective incorporation of selenium into proteins for X-ray crystallography studies (MAD phasing).
• Antioxidant Studies: Utilized in research models to explore the antioxidant properties and redox biology of selenium compounds.
• Reference Standard: Acts as a high-purity analytical standard for quality control in related chemical and pharmaceutical manufacturing.
