Glutathione, commonly abbreviated as GSH, is a tripeptide composed of glutamate, cysteine, and glycine and supplied for controlled laboratory, analytical, and scientific research.
Unlike conventional peptides, glutathione contains an unusual γ-glutamyl linkage between the glutamate side-chain carboxyl group and the amino group of cysteine. This structural feature is central to its chemical identity.
For accurate documentation, the oxidation state, chemical form, purity specification, and lot-specific analytical profile should be confirmed using the applicable Certificate of Analysis.
Research Applications
Reduced glutathione may be examined in controlled non-clinical research involving:
- Tripeptide characterization
- Redox chemistry research
- Thiol-associated biochemical studies
- Enzyme interaction research
- Molecular stability studies
- Analytical chemistry
- Comparative biochemical analysis
- Non-clinical cellular models
Experimental observations should remain specific to the applicable research system and should not be interpreted as evidence of detoxification, cosmetic benefit, therapeutic effectiveness, or clinical suitability.
Structural Information
Reduced glutathione consists of:
γ-Glu-Cys-Gly
Expanded representation:
γ-L-Glutamyl-L-cysteinylglycine
Important structural characteristics include:
- Three amino-acid residues
- A γ-glutamyl peptide linkage
- A cysteine thiol group
- Reduced chemical state
The reduced form GSH should be distinguished from oxidized glutathione (GSSG), which has a different molecular structure, molecular formula, and molecular weight.
Analytical Identification
Relevant analytical characterization may include:
- Chemical identity confirmation
- Molecular mass assessment
- Reduced/oxidized state determination
- Chromatographic purity testing
- Thiol-content analysis
- Spectrometric characterization
- Lot-specific quality testing
Specifications & Documentation
Lot-specific documentation should be reviewed for:
- Compound identity
- Reduced or oxidized state
- Molecular formula
- Molecular weight
- Purity specification
- 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 may promote oxidation or otherwise compromise chemical integrity.
Handling should follow established laboratory procedures appropriate for biochemical research materials.
