Its defining structural feature is the gamma peptide bond linking the glutamate side-chain carboxyl to cysteine, which renders it resistant to cleavage by standard intracellular peptidases. The free cysteine thiol is the reactive centre responsible for its redox chemistry.\u003c\/p\u003e\u003cp\u003eGlutathione is the principal intracellular redox buffer, cycling between its reduced (GSH) and oxidised disulfide (GSSG) forms. It is a standard reagent and reference compound in research on reactive oxygen species scavenging, glutathione peroxidase and glutathione S-transferase enzymology, xenobiotic conjugation and phase II detoxification, and the GSH\/GSSG ratio as a marker of cellular redox state. Biosynthesis proceeds via glutamate-cysteine ligase (the rate-limiting step) and glutathione synthetase, with regeneration from GSSG catalysed by NADPH-dependent glutathione reductase.\u003c\/p\u003e\u003cp style=\"font-size:0.875em;border:1px solid #dde6f0;padding:10px;border-radius:4px;\"\u003e\u003cstrong\u003eCAS:\u003c\/strong\u003e 70-18-8  ·  \u003cstrong\u003eFormula:\u003c\/strong\u003e C₁₀H₁₇N₃O₆S  ·  \u003cstrong\u003eMW:\u003c\/strong\u003e 307.32 g\/mol  ·  \u003cstrong\u003eFormat:\u003c\/strong\u003e Lyophilised powder  ·  \u003cstrong\u003eStorage:\u003c\/strong\u003e −20 °C, protected from light\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eResearch Areas:\u003c\/strong\u003e Cellular redox homeostasis · ROS scavenging · GSH\/GSSG ratio · Glutathione peroxidase \u0026amp; S-transferase enzymology · Xenobiotic conjugation · Oxidative stress models · Mitochondrial redox signalling\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eResearch Literature:\u003c\/strong\u003e\u003cbr\u003e• \u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=glutathione+GSH+GSSG+oxidative+stress+redox+homeostasis\" target=\"_blank\" rel=\"noopener\"\u003ePubMed: Glutathione research literature →\u003c\/a\u003e\u003c\/p\u003e\u003cp style=\"background:#eef4fb;border-left:3px solid #0b4a7c;padding:10px 14px;margin-bottom:1em;font-size:0.875em;\"\u003e\u003cstrong\u003eMulti-Buy Savings\u003c\/strong\u003e — Add 2+ products to save 4% automatically.
