Glutathione

Glutathione (GSH) is the most abundant non-protein thiol in mammalian cells. This reduced γ-linked tripeptide (L-γ-glutamyl-L-cysteinyl-glycine) is a well-characterized molecule that has been extensively studied in the context of redox biology. As documented in the peer-reviewed literature, GSH serves as a cofactor for glutathione peroxidase (GPx) and glutathione S-transferase (GST), and plays a central role in cellular redox homeostasis (ncbi.nlm.nih.gov, pmc.ncbi.nlm.nih.gov). This research-grade lyophilized powder is produced under strict quality standards and includes full analytical documentation, making it suitable for in-vitro oxidative stress, redox signaling, and detoxification pathway research.
