Research Background

Glutathione is the most abundant intracellular non-protein thiol and the body primary endogenous antioxidant. The GSH/GSSG ratio serves as a key indicator of cellular redox status. GSH functions through direct ROS scavenging, serving as cofactor for glutathione peroxidase, conjugating xenobiotics via GST, and maintaining protein thiol redox state.

The 600 mg configuration is manufactured under strict quality control with HPLC, MS, and AAA verification. Batch-specific COA included. Bulk and OEM configurations available.

Molecular Mechanisms

Direct ROS Scavenging

Thiol group directly reduces H2O2, superoxide, hydroxyl radical, and peroxynitrite.

GPx Cofactor

Glutathione peroxidase uses GSH as electron donor: 2 GSH + H2O2 to GSSG + 2 H2O. GSSG recycled by glutathione reductase using NADPH.

Xenobiotic Detoxification

GST conjugates GSH to electrophilic xenobiotics for mercapturic acid excretion. Major Phase II detoxification pathway.

Research Applications

Cellular Redox Biology
Oxidative Stress Research
GPx/GST Detoxification Pathways
Protein Thiol Redox Regulation

Comparative Analysis

Compared to NAC: NAC is a GSH precursor requiring biosynthesis. GSH is the active antioxidant. NAC = prodrug; GSH = direct antioxidant cofactor.
