L-Glutathione

L-Glutathione Overview

L-Glutathione is a ubiquitous tripeptide present in virtually all living organisms, serving as a primary intracellular antioxidant and redox regulator. In its reduced form (GSH), it participates in neutralizing reactive oxygen species (ROS), maintaining redox homeostasis, and supporting the integrity of proteins, lipids, and DNA against oxidative stress. Through its sulfhydryl group on the cysteine residue, glutathione acts as a substrate for peroxidase enzymes that reduce hydrogen peroxide and lipid peroxides. Research models examine its role in phase II conjugation pathways, molecular proliferation and signaling, mitochondrial function, and protein folding regulation in laboratory settings.Forman et al. (2009). Lu (2013).
