Glutathione is an endogenous tripeptide, gamma-glutamyl-cysteinyl-glycine. It occurs naturally in cells and is one of the most extensively characterised molecules in cellular biochemistry.
Molecular target
Not a receptor ligand. Glutathione functions as the principal low-molecular-weight thiol buffer of the cytosol.
Signalling pathway
Serves as substrate for glutathione peroxidases and glutathione S-transferases. The ratio of reduced to oxidised glutathione is a standard laboratory readout of cellular redox state.
Research context
Core biochemistry and cell biology, where it is used both as a reagent and as a measured endpoint. Well characterised as an endogenous molecule.
