Glutathione
1. Basic Information
Name: Glutathione
Alias: γ-L-Glutamyl-L-cysteinylglycine, GSH
CAS No.: 70-18-8
Molecular Formula: C10H17N3O6S
Molecular Weight: 307.33
2. Physical and Chemical Properties
Physical Properties
- Appearance: White crystalline powder
- Odor: Odorless, slight sour taste
- Solubility: Freely soluble in H2O; slightly soluble in CH3OH; insoluble in C2H5OH, acetone and lipid solvents
- Melting Point: Decomposes above 190 °C without clear melting point
- Hygroscopicity: Moderately hygroscopic under high humidity
- Aqueous Characteristic: Weakly acidic aqueous solution with strong reducing property
Chemical Properties
- Molecular Structure: Tripeptide composed of glutamic acid, cysteine and glycine, containing active sulfhydryl group (-SH)
- Reducing Activity: The sulfhydryl group easily oxidizes under air and UV light to form oxidized glutathione (GSSG)
- Acid-base Stability: Stable under weak acidic environment; rapidly hydrolyzed under strong acid or alkaline heating
- Thermal Stability: Stable below 40 °C; high temperature accelerates oxidation and peptide bond cleavage
- Photostability: Highly sensitive to ultraviolet light; long-term illumination loses activity and turns yellow
- Compatibility: Incompatible with strong oxidants, heavy metal ions and alkaline substances
