Glutathione 600mg is supplied strictly for laboratory research use only. This material is intended for analytical and controlled research applications. It is not approved or intended for human or animal use, ingestion, dosing, or therapeutic application. Glutathione is a tripeptide (glutamate–cysteine–glycine) widely used as a reference compound in redox-biology and enzymology research. Published in-vitro literature has characterised it in the following experimental contexts: Redox chemistry. The reduced (GSH) and oxidised (GSSG) forms are commonly quantified as a ratio in cell-culture models used to describe oxidative state. Interconversion between the two forms is catalysed by glutathione reductase. Conjugation chemistry. Glutathione S-transferase enzymes catalyse conjugation of glutathione to electrophilic substrates, a reaction frequently used in enzymology and metabolite-identification assays. Antioxidant cycling models. Its chemical interaction with ascorbate and tocopherol has been described in model systems. Cell-signalling literature. Intracellular glutathione concentration is reported as an experimental variable in published lymphocyte and natural-killer-cell assay models. Enzyme-inhibition literature. Interaction with tyrosinase has been described in in-vitro pigment-chemistry studies. The material is produced as a high-purity research reagent under controlled conditions, with batch-level quality control to support reproducibility across laboratory studies.
