A clear L-Glutathione research vial on a coloured plaster ledge, with botanicals beside it

About this compound

L-Glutathione is a tripeptide with an unusual structural feature: the bond between glutamate and cysteine is a gamma-peptide linkage through the glutamate side-chain carboxyl rather than the standard alpha-peptide bond.

Studied in

Redox balance
Detoxification pathways
Oxidative-stress models
