Reduced Glutathione, N (N-L-γ-Glutamyl-L-cysteinyl) glycine

C₁₀H₁₇N₃O₆S（307.32）

Structure features:

1. A thiol group, which is responsible for anti-oxidation and detoxification activity.

2. A unique amide bond, which just can be hydrolyzed by γ-glutamyl transferase existing in lateral cell membrane. That's why GSH is more stable in cell than other tri-peptides.
