Tripeptide · research grade
For laboratory research use only. Not for human consumption.
A tripeptide. CAS and molecular formula: [VERIFY].
Supplied for laboratory research use. No third-party certificate of analysis has been published for this compound yet, so no purity figure is claimed for it. A published HPLC certificate will accompany it once a batch is tested.
Supplied as a lyophilized powder. Store at −20°C, desiccated and protected from light. Handled per the receiving laboratory's protocols. Not for human consumption.
Chemical identifiers marked [VERIFY] are pending verification and must not be treated as confirmed.
Also known asGSH · L-Glutathione reduced · Reduced glutathione · gamma-Glutamylcysteinylglycine
Glutathione (GSH) is a tripeptide of glutamate, cysteine, and glycine, supplied as a lyophilized powder for laboratory research use only. Almost all of the literature published under its name concerns the glutathione that cells make for themselves — the endogenous pool — which is a distinct subject from the exogenous tripeptide listed here.
The endogenous pool is assembled inside the cell in two ATP-dependent steps, by glutamate-cysteine ligase and then glutathione synthetase, and is partitioned across cytosolic, mitochondrial, and nuclear compartments by specific transport rather than by free diffusion. A concentration measured in any one compartment therefore reflects synthesis, consumption, and export within that compartment.
The intact tripeptide is not generally carried across the plasma membrane. Extracellular gamma-glutamyl transpeptidase cleaves it to its constituent amino acids, which are taken up and re-assembled inside the cell, so an exogenous molecule and the intracellular pool are linked by degradation and resynthesis rather than by direct transfer.
The availability literature is correspondingly mixed and route-dependent: a single large oral load of glutathione did not raise plasma concentration in a 1992 report, while dietary glutathione was described as absorbed intact in a 1990 rat study. Findings about endogenous status do not carry over to the exogenous compound unless that step is established separately.
Reported mechanism · literatureIn biochemistry glutathione is described as the principal low-molecular-weight thiol redox couple, cycling between its reduced (GSH) and disulfide (GSSG) forms and acting as cofactor for the glutathione peroxidase and glutathione S-transferase enzyme families. That description is of the endogenous pool, and is not a statement about the exogenous compound.

Species in the cited literaturePublished research involving Glutathione includes work carried out in dogs, cats, horses. This records which animals the cited work used — the same kind of fact as a journal or a year. It is not a statement about outcomes, and nothing here is veterinary guidance.

Glutathione (GSH) is a tripeptide of glutamate, cysteine, and glycine, with the gamma-linkage between glutamate and cysteine that distinguishes it from an ordinary peptide bond. Ouralus supplies it as a lyophilized powder for laboratory research use only.
Mostly it is not. The large majority of it measures the endogenous pool that cells synthesize themselves, which is governed by the two-enzyme synthesis pathway inside the cell. The intact tripeptide is not generally carried across the plasma membrane — extracellular gamma-glutamyl transpeptidase cleaves it into amino acids that are then re-imported and re-assembled. Endogenous-status findings therefore do not transfer to the exogenous compound on their own.
C10H17N3O6S (molar mass ≈ 307.3 g/mol; PubChem CID 124886, CAS 70-18-8, UNII GAN16C9B8O). This is the reduced (GSH) form; the oxidized disulfide GSSG is a different molecule with roughly twice the mass.
These materials are supplied strictly for laboratory and research use, to purchasers of legal age. They are not supplements, drugs, or foods, and are not for human or animal consumption.
Glutathione is supplied strictly as a research chemical for laboratory research use only — it is not a drug, supplement, or food, and not for human or animal consumption. It ships to purchasers of legal age for research use. Buyers are responsible for compliance with the laws that apply to research materials in their own jurisdiction.
Ouralus third-party HPLC-tests its catalogue lots and publishes the certificate of analysis per product as each report is finalized. A certificate is not posted for Glutathione yet, so treat its identity and purity as unconfirmed until one appears here. Supplied as a research chemical for laboratory use only.
