Think of oxidative stress as the "wear and tear" that happens at a cellular level due to environmental pollutants, processed foods, and the natural process of aging
GSH exerts its action as skin whitening agent at various levels of melanogenesis which include the following: [1],[3] Interference with cellular transport of tyrosinase Direct inactivation of the enzyme tyrosinase by binding with the copper-containing active site of the enzyme Mediating the switch mechanism from eumelanin to phaeomelanin production as GSH is the major physiologic reservoir of cysteine and increase in cysteine levels results in switching of eumelanogenesis to pheomelanogenesis [Figure - 1] Quenching of free radicals and peroxides that contribute to tyrosinase activation and melanin formation Modulation of depigmenting abilities of melanocytotoxic agents

For UPLC-MS/MS experiments, the product ion mass spectra were acquired with collision cell voltages between 10 and 30 V, depending on the analyte
Applied twice daily using 0.5ml per application, this provides 20mg per day of topical peptide (though actual absorption is much lower due to skin penetration limits)
Conversely, if there is no need for further ATP production, the carbon skeleton of pyruvate can be diverted into various biosynthetic pathways
