What it does
Meet your product.
Glutathione is a tripeptide studied in cellular redox chemistry and biochemical assays. Available from pepfine for laboratory research.
At pepfine, we offer this product as a research-use-only material intended for controlled laboratory studies. This product is strictly not intended for human consumption, clinical treatment, or veterinary use.
Research Background
Its constituent amino acids are glutamate, cysteine, and glycine. Reduced and oxidized glutathione are distinct analytical species, so the form supplied matters when interpreting an experiment.
Areas of Active Research
- Cellular Redox Balance: Laboratory research examines reduced and oxidized glutathione as distinct participants in redox chemistry. Measuring their relationship helps characterize biochemical conditions within an experimental system.
- Glutathione-Dependent Enzymes: Studies investigate reactions that use glutathione in redox and conjugation processes. Its chemical form and oxidation state are important when selecting material for a particular assay.
- Metabolite Analysis: Analytical methods quantify glutathione and related species. These measurements help researchers distinguish changes in glutathione availability from differences in sample composition or degradation.
Mechanism of Action
The cysteine thiol group participates in redox reactions and conjugation chemistry. Product identity and oxidation state should be confirmed for assays that require a particular form.
Available Sizes
The following options are listed in this catalog:
- Glutathione 200 mg
- Glutathione 500 mg
The supplied oxidation state and salt form are not specified in the catalog.
