Tripeptide antioxidant (GSH)
Glutathione
Principal intracellular thiol buffer used by glutathione peroxidases and S-transferases; exogenous GSH has limited intact cellular uptake.
Primary Mechanism of Action
Clinical / Scientific
GSH reduces hydrogen peroxide and lipid hydroperoxides via glutathione peroxidases and conjugates electrophiles via GSTs. Extracellular or IV glutathione does not freely enter all cells; some effects may be extracellular redox or breakdown to amino acids (including cysteine) that then rebuild intracellular GSH.
Pathway Targets
Oxidative stress signalling
Scientific explanation
Peroxide detoxification via GPx.
Electrophile conjugation
Scientific explanation
GST-dependent detoxification.
Pathway Convergence
Clinical / Scientific
Target → pathway → downstream effect → biological consequence. This is a mechanistic map, not a treatment claim.
Receptor to physiology
Target to downstream effect: Oxidative stress signalling → Electrophile conjugation

In Plain Language
Glutathione is the cell’s main reusable antioxidant. Injecting it is not the same as packing every cell with GSH, because many cells do not import the intact tripeptide well.
