Product Overview

L-Glutathione, biochemically designated as γ-L-glutamyl-L-cysteinylglycine, is the predominant low-molecular-weight thiol found in virtually all eukaryotic cells. As the principal intracellular antioxidant tripeptide, it plays a central role in maintaining cellular redox homeostasis, supporting mitochondrial enzyme function, and neutralizing electrophilic metabolites generated during oxidative stress events. The Peptide Store supplies this foundational research reagent in a precision-measured lyophilized format, offering biochemistry, toxicology, and cellular biology laboratories a rigorously quality-controlled baseline compound for advanced mechanistic studies.

Peptide Structure & Amino Acid Sequence

L-Glutathione is a linear tripeptide composed of three amino acid residues: L-glutamate, L-cysteine, and glycine. Its defining structural feature is the atypical gamma-peptide bond formed between the side-chain carboxyl group of glutamate and the alpha-amine of cysteine. This non-standard linkage confers exceptional resistance to intracellular aminopeptidase-mediated hydrolysis, granting L-Glutathione a metabolic stability profile that distinguishes it from conventional alpha-linked dipeptides and tripeptides. The free sulfhydryl (-SH) group on the cysteine residue is the primary reactive site responsible for its nucleophilic and reducing properties, enabling electron donation in enzymatic and non-enzymatic antioxidant reactions.

Purity & Analytical Verification (HPLC & MS)

Every batch of L-Glutathione 600mg supplied by The Peptide Store undergoes rigorous analytical testing to confirm identity and purity. High-Performance Liquid Chromatography (HPLC) is employed to quantify purity at ≥98%, ensuring minimal presence of related impurities, synthetic by-products, or degradation fragments. Mass Spectrometry (MS) analysis confirms the correct molecular weight and structural integrity of the tripeptide sequence. Researchers can rely on these dual verification methods as the gold standard for research-grade compound authentication, supporting reproducible experimental outcomes across independent laboratory settings.

Quality Control & Lyophilization Integrity

L-Glutathione 600mg is produced under stringent quality control protocols governing synthesis, purification, and final formulation. The lyophilization process removes residual moisture to below critical thresholds, preserving the structural integrity of the thiol-containing cysteine residue and preventing premature oxidation of the free sulfhydryl group during storage and transit. Each production lot is individually tracked, with batch-specific analytical data available upon request. This commitment to quality control ensures that researchers receive a consistent, stable, and scientifically reliable reagent with every order placed at The Peptide Store.

Safety, Handling & Laboratory Precautions

As with all research-grade biochemical compounds, standard laboratory safety protocols must be observed when handling L-Glutathione 600mg. Researchers should utilize appropriate personal protective equipment (PPE), including nitrile gloves, laboratory coat, and eye protection. The compound should be handled in a well-ventilated environment or within a certified fume hood where applicable. Avoid prolonged exposure to atmospheric oxygen prior to reconstitution to preserve thiol group integrity. All waste disposal must comply with institutional biosafety guidelines and applicable local regulations governing research chemical management.

Reconstitution, Packaging & Storage

L-Glutathione 600mg is supplied as a lyophilized powder in a sealed, inert-atmosphere vial designed to minimize pre-reconstitution oxidation. For laboratory reconstitution, researchers should consult peer-reviewed literature and institutional SOPs relevant to their specific assay requirements. The compound is best stored at -20°C in a dry, dark environment, away from repeated freeze-thaw cycling. Once reconstituted, aliquoting into single-use volumes is strongly recommended to preserve compound stability across the duration of the research project. Packaging is designed to meet international shipping standards for research reagents.

Intended Research Use & Market Positioning

L-Glutathione 600mg is positioned as an essential reference compound for investigators working across redox biology, mitochondrial biochemistry, lipid peroxidation research, Phase II detoxification studies, and γ-glutamyl cycle kinetics. It is widely utilized in cell-free enzymatic assays, cell lysate preparations, and in vitro oxidative stress models. The Peptide Store offers this reagent as a best-price, high-purity option for academic institutions, contract research organizations (CROs), and independent research laboratories seeking a dependable supply of analytically verified glutathione for ongoing or exploratory research programs.
