Product Description
Synthetic Tripeptide for Oxidative Stress Research
Technical Overview
L-Glutathione 600mg is a synthetic peptide compound developed for laboratory research involving redox biology and thiol-disulfide exchange, receptor interaction analysis, and controlled experimental investigation. In research settings, this peptide is commonly utilized for studying intracellular antioxidant capacity, glutathione S-transferase conjugation reactions, and related biochemical mechanisms.
L-Glutathione (GSH) is the reduced tripeptide gamma-L-glutamyl-L-cysteinyl-glycine and the primary endogenous low-molecular-weight thiol antioxidant. Its cysteinyl thiol group neutralizes reactive oxygen species, donates electrons in glutathione peroxidase reactions, and forms conjugates with electrophilic xenobiotics via glutathione S-transferases.
Investigators use GSH to model cellular redox homeostasis, study Phase II detoxification pathways, and probe protein S-glutathionylation as a post-translational regulatory mechanism. It also serves as a standard for quantifying intracellular GSH:GSSG ratios in oxidative-stress assays.
This compound is synthesized using established solid-phase peptide synthesis methods and purified through reversed-phase HPLC to achieve analytical purity suitable for laboratory assays, binding studies, and analytical applications. The lyophilized material is supplied for reconstitution per established laboratory protocols and is intended as a reference material in controlled research environments.
