L-Glutathione (reduced glutathione, GSH) is a naturally occurring tripeptide composed of L-glutamate, L-cysteine, and glycine, joined through an unusual γ-glutamyl bond. It is among the most abundant intracellular antioxidants and functions as a central component of the cellular redox system, serving as a substrate for glutathione peroxidase and glutathione S-transferase enzymes across antioxidant, oxidative-stress, and detoxification research.

BENEFITS

• Antioxidant defense — studied as a primary intracellular scavenger of reactive oxygen species (ROS)

• Redox balance — investigated for its role in maintaining the cellular GSH/GSSG ratio

• Detoxification research — examined as a cofactor in phase II conjugation and xenobiotic clearance

• Cysteine delivery — studied as a transport and storage form of bioavailable cysteine

• Cellular protection — explored in models of oxidative and electrophilic stress

WHAT RESEARCHERS LOOK AT

• GSH/GSSG ratio as a marker of cellular redox state

• Glutathione peroxidase and glutathione reductase enzyme activity

• Conjugation reactions catalyzed by glutathione S-transferases

• Mitochondrial glutathione pools and oxidative-stress resistance

• Depletion and repletion kinetics in cell-culture models
