Chemical Basis: From Tripeptide Core to S-Acetylation The Tripeptide Core: The Common Foundation of Both L-Glutathione and S-Acetyl-L-Glutathione L-Glutathione(GSH) and S-acetyl-L-Glutathione(SAG) share an identical tripeptide core structure: -glutamyl-cysteinyl-glycine
Esterified versions such as acetyl-L-carnitine have different volatility and degradation profiles, which changes their scent
