China [CN]

Basic Information

English: S-Acetyl-L-glutathione

Abbreviation: S-Acetyl GSH

Molecular Formula: C₁₂H₁₉N₃O₇S

Molecular Weight: 347.36

CAS Number: 3054-47-5

Structure and Characteristics

A precursor/modified form of L-glutathione

Acetyl protection on the thiol group (-SH)

Far higher stability than ordinary reduced GSH

Advantages

More stable

Less prone to oxidation and inactivation, more storage- and formulation-friendly.

Better absorption

Stronger cell membrane penetration, higher oral/topical bioavailability.

Intracellular deacetylation

Releases active L-glutathione after entering the cell to exert its effect.
