Glutathione is a tripeptide made from glutamic acid, cysteine and glycine, joined by an unusual gamma-glutamyl bond. In its reduced form (GSH) the cysteine's thiol group is free, and it is the most abundant small thiol in animal cells. Frederick Gowland Hopkins isolated and named it in 1921.
It is a standard subject in oxidative stress and redox research, where the ratio of reduced to oxidised glutathione is a common measure of a cell's redox state.
