Description

Cysteinylhomocysteine Mixed Disulfide is a critical biochemical compound formed from the oxidation of cysteine and homocysteine thiol groups. This molecule serves as a key intermediate and biomarker in the study of sulfur amino acid metabolism and associated redox biology. It is essential for researchers and manufacturers in the pharmaceutical and life science sectors focused on cardiovascular health, metabolic disorders, and oxidative stress pathways. Our supply ensures high-purity material to support reliable and reproducible scientific and industrial outcomes.

Application

• Biochemical Research: Used as a standard and reagent in studies of homocysteine metabolism, transsulfuration pathways, and redox state regulation.
• Diagnostic Development: Serves as a critical reference compound and calibrant for assays measuring homocysteine-related metabolites in clinical samples.
• Pharmaceutical Intermediates: Acts as a potential building block or precursor in the synthesis of novel therapeutic agents targeting cardiovascular and neurological diseases.
• Nutritional Science: Employed in research investigating the biochemical impact of B-vitamin deficiencies (e.g., B6, B12, folate) on sulfur amino acid cycles.
• Toxicology Studies: Utilized to investigate the mechanisms of hyperhomocysteinemia and its role in endothelial dysfunction and vascular injury.
• Enzymology: Serves as a substrate or inhibitor for enzymes involved in disulfide bond reduction and thiol-disulfide exchange reactions.
