Research Overview
L-Glutathione (reduced form, GSH) is a naturally occurring tripeptide composed of glutamate, cysteine, and glycine. It is the most abundant intracellular antioxidant in mammalian cells and is widely used in oxidative-stress, detoxification, and redox-biology research.
Mechanism of Action
Acts as the primary substrate for glutathione peroxidase and glutathione-S-transferase enzyme systems in research models, neutralizing reactive oxygen species and conjugating xenobiotic intermediates.
Research Applications
- Oxidative-stress assays
- Redox-biology research
- Phase II detoxification studies
