S -Glutathioylation of Proteins: A Crucial Modulating Factor Besides acting as a reactive oxygen scavenger, GSH can also form mixed disulfides with proteins, a process known as S -glutathionylation or reversible protein glutathionylation (Figure 1)
It helps protect your cells from damage caused by harmful molecules called free radicals

Its various mechanisms, including its antioxidant effects, the stimulation of pheomelanin synthesis instead of eumelanin, and interference with intracellular trafficking of melanogenic enzymes, contribute to its antimelanogenic properties
The study findings demonstrated that oxidative stress occurs early in pregnancies affected by trisomy 21 (T21), as evidenced by increased protein oxidation, lipid peroxidation, reduced levels of GSH and TRX, and the induction of the HSP response
