What Is Glutathione?

Research overview

Glutathione is a tripeptide (gamma-glutamyl-cysteinyl-glycine) and the cell's principal endogenous antioxidant, central to redox-balance and detoxification research.

  • Endogenous tripeptide antioxidant (GSH)
  • Studied for redox balance, detoxification, and cysteine handling
  • A core molecule in oxidative-stress research
  • Supplied strictly as a research-grade reference material

Research Applications

Studied in preclinical research models · not for human use

Antioxidant research

Studied for neutralization of reactive oxygen species and redox balance.

Detoxification models

Examined for conjugation reactions in xenobiotic and detox pathways.

Redox-signaling studies

Investigated for the GSH/GSSG ratio as a cellular redox indicator.

Cellular-stress research

Explored for protection against oxidative damage in cell models.

Proposed Mechanisms

Preclinical · proposed pathways

ROS neutralization

Donates electrons to neutralize reactive oxygen species, becoming oxidized (GSSG).

Glutathione cycle

Regenerated from GSSG by glutathione reductase using NADPH.

Conjugation / detox

Acts as a substrate for glutathione-S-transferases in detoxification.

Thiol buffering

Its cysteine thiol maintains protein redox state and cellular thiol balance.

Mechanisms described above are drawn from preclinical (cell and animal) research and, where noted, early clinical literature. They are provided for educational context and should not be read as clinical or therapeutic claims.

Frequently Asked Questions

Glutathione
Is Glutathione for human use?
No. It is supplied strictly as a research-grade reference material for laboratory use, not for human or animal consumption.
What is glutathione made of?
It is a tripeptide of glutamate, cysteine, and glycine, with the cysteine thiol carrying its antioxidant activity.
What purity is the material?
Each batch is independently tested and ships with a batch-specific Certificate of Analysis at greater than or equal to 99% purity by HPLC.
How is it stored?
Store the lyophilized material at -20°C; once in solution, keep at 2-8°C and avoid repeated freeze-thaw cycles.
