Tripeptide · redox cofactor.
Glutathione is the most abundant intracellular antioxidant in mammalian cells and a central cofactor of cellular redox biology. A tripeptide with an unusual γ-linkage between glutamate and cysteine, it exists primarily in the reduced GSH form. Supplied as research-grade material with 3rd-party HPLC verification and full Certificate of Analysis per lot.
Glutathione is the most abundant intracellular antioxidant in mammalian cells and a central cofactor of cellular redox biology. A tripeptide with an unusual γ-linkage between glutamate and cysteine, it exists primarily in the reduced GSH form.
Functions as the principal intracellular reducing agent via the thiol group of its cysteine residue. Central to detoxification (glutathione S-transferase conjugation of xenobiotics), antioxidant defense (glutathione peroxidase substrate), and protein function (S-glutathionylation as a redox regulatory modification).
Used clinically (IV and oral) for various conditions including Parkinson's disease research, autism research, and liver disease. Bioavailability is generally poor via oral routes; parenteral and liposomal formulations are commonly used in research.
The above summarizes published research literature. This is not medical advice, a protocol, or a recommendation for use. This compound is supplied for laboratory research only.
Glutathione is a 3-residue peptide with molecular formula C10H17N3O6S and molecular weight of approximately 307.3 Da.
The full structural data and release specifications are in the Compound Profile section above. Every lot ships with an independently verified Certificate of Analysis.
Each lot is independently verified by a 3rd-party analytical laboratory (STERIS Labs, Alcami Analytical, or equivalent) before release. Release specification is HPLC purity ≥ 99.5% (typical > 99.8%), mass spectrometry identity match within ±0.5 Da, water content < 5.0% Karl Fischer, and endotoxin < 0.25 EU/mL by LAL (USP <85>).

All compounds ship at ambient temperature in discreet, tamper-evident packaging. Lyophilized peptide powder is stable at room temperature for typical transit windows, which is why research-grade vendors ship this way. Tracked; signature not required.
Store unopened lyophilized product at 2–8°C protected from light. Once reconstituted, most peptides are stable at 2–8°C for approximately 28 days (compound-dependent).
Used clinically (IV and oral) for various conditions including Parkinson's disease research, autism research, and liver disease. Bioavailability is generally poor via oral routes; parenteral and liposomal formulations are commonly used in research.
All PeptideBros compounds are sold strictly as chemical reference materials for in-vitro laboratory research. They are not for human consumption.
HPLC-verified. Mass-spec confirmed. Ambient-stable transit. The paperwork other vendors hope you never ask for.
