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

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.
