Pitfalls in the analysis of the physiological antioxidant glutathione (GSH) and its disulfide (GSSG) in biological samples: an elephant in the room

Subsequent research revealed that GHK could influence various cell types beyond liver cells

For example, the tripeptide glutathione is synthesized in two steps from free amino acids, by two enzymes: glutamatecysteine ligase (forms an isopeptide bond, which is not a peptide bond) and glutathione synthetase (forms a peptide bond)
