Glutathione

Description

Glutathione is a naturally occurring tripeptide composed of glutamate, cysteine, and glycine. In reduced glutathione, the glutamate and cysteine residues are connected through a characteristic gamma-glutamyl linkage, distinguishing its structure from conventional peptide bonds. Synthetic or purified glutathione research material is utilized in controlled laboratory environments for analytical, biochemical, redox-chemistry, and molecular investigation. The material may be supplied as a lyophilized powder or crystalline solid depending on the manufacturer and formulation.

Research Applications:

Glutathione may be utilized in controlled laboratory research settings for applications such as:

• Analytical characterization of tripeptide identity, purity, and physicochemical properties
• Investigation of thiol-dependent redox reactions in controlled biochemical systems
• Evaluation of oxidation-reduction behavior and conversion between reduced and oxidized glutathione forms
• Examination of glutathione-related molecular interactions in biochemical and cell-based laboratory assays

Storage and Handling:

• Store according to the conditions specified in the batch-specific supplier documentation or Certificate of Analysis.
• For long-term storage of research-grade material, -20°C may be recommended depending on the specific formulation.
• Protect the material from excessive moisture, heat, light, and prolonged air exposure.
• Prepared solutions may undergo oxidation over time and should be handled according to validated stability data and the requirements of the specific laboratory protocol.
• Use appropriate laboratory handling procedures to minimize contamination and preserve material integrity.

Product Specifications:

• Purity: Refer to batch-specific HPLC or other analytical results and Certificate of Analysis
• Appearance: Typically supplied as a white to off-white powder or lyophilized solid; confirm against batch-specific documentation
• Solubility: Generally soluble in aqueous laboratory systems, although actual solubility depends on concentration, pH, formulation, and solvent conditions

Compliance Notice:

Glutathione is FOR RESEARCH USE ONLY. It is not intended for human or veterinary use. This product is supplied exclusively for controlled laboratory, analytical, and in vitro research purposes and is not intended for diagnostic, therapeutic, or clinical applications. Misuse of this product is strictly prohibited and may violate applicable federal, state, or local laws. By purchasing this product, the buyer represents and warrants that it will be used solely for legitimate laboratory research purposes.

Technical Note: The molecular formula C₁₀H₁₇N₃O₆S and molecular weight of approximately 307.32 g/mol correspond specifically to reduced glutathione (GSH). Oxidized glutathione (GSSG) is a different molecular species formed through a disulfide linkage between two glutathione molecules and therefore has different molecular specifications. Final product-page information should confirm whether the supplied material is GSH or GSSG and should match the exact purity, formulation, physical form, and analytical values listed in the supplier documentation and batch-specific Certificate of Analysis (COA).
