Description

S-Adenosyl-L-Cysteine is a crucial biochemical cofactor and metabolite derived from the amino acid L-cysteine and adenosine triphosphate (ATP). This compound matters significantly as a key intermediate in cellular transsulfuration pathways and a potential source of cysteine and glutathione, playing a vital role in maintaining redox balance and cellular defense mechanisms. It is primarily needed by manufacturers in the pharmaceutical, nutraceutical, and research biochemical sectors for applications in metabolic studies, supplement formulation, and as a reference standard.

Application

• Pharmaceutical Intermediate: Used in the research and development of drugs targeting metabolic disorders, liver health, and neurological conditions.
• Nutraceutical Ingredient: Incorporated into dietary supplements for its role in supporting glutathione synthesis and antioxidant defense systems.
• Biochemical Research: Serves as a critical reagent and standard in studies of methylation cycles, sulfur amino acid metabolism, and redox biology.
• Cell Culture Supplement: Utilized in specialized media formulations to support the growth and study of certain cell lines under oxidative stress.
• Reference Standard: Employed in analytical laboratories for quality control and method validation using techniques like HPLC and LC-MS.
