Description
Glutathione, commonly abbreviated as GSH, is a chemically defined tripeptide composed of glutamate, cysteine, and glycine. It is supplied for controlled laboratory, analytical, and scientific research.
A distinguishing structural feature of glutathione is the gamma-glutamyl linkage between glutamate and cysteine, which differs from a conventional alpha-peptide bond. This structural arrangement forms an important part of its chemical identity and should be considered during analytical characterization.
Reduced glutathione should also be clearly distinguished from oxidized glutathione (GSSG), which has a different molecular structure and analytical profile.
Research Applications
Glutathione may be examined in controlled non-clinical research involving:
- Tripeptide characterization
- Redox-state analysis
- Molecular interaction studies
- Comparative biochemical research
- Structural characterization
- Chromatographic analysis
- Spectrometric identification
- Stability assessment
- Non-clinical biochemical and cellular models
Experimental observations should remain specific to the applicable research system and should not be interpreted as evidence of antioxidant, detoxification, cosmetic, therapeutic, or clinical effectiveness.
Structural Information
Glutathione is commonly represented as:
γ-Glu-Cys-Gly
Key structural characteristics include:
- Three amino-acid residues
- Gamma-glutamyl linkage
- Cysteine thiol functionality
- Reduced molecular state
- Defined tripeptide architecture
Do not confuse the reduced form, GSH, with the disulfide-linked oxidized form, GSSG.
Analytical Identification
Relevant analytical characterization may include:
- Chemical identity confirmation
- Molecular-mass assessment
- Reduced-state verification
- Thiol-content analysis
- Chromatographic purity testing
- Spectrometric characterization
- Related-substance analysis
- Lot-specific quality testing
Specifications & Documentation
Lot-specific documentation should be reviewed for:
- Glutathione identity
- Reduced or oxidized state
- CAS number
- Molecular formula
- Molecular weight
- Purity specification
- Related substances
- Analytical testing
- Lot or batch information
- Certificate of Analysis
- Storage requirements
Authenticated product-specific documentation should take precedence over generalized reference values.
Storage & Handling
Store according to the conditions specified on the product label and Certificate of Analysis. Protect the material from environmental conditions that could compromise chemical integrity or oxidation state.
Handling should follow established laboratory procedures appropriate for peptide and biochemical research materials.
