Upon its efflux from cells, oxidised glutathione is exposed to the sequential action of enzymes located on the external face of the cell membrane: -glutamyl transpeptidase (GGT) generates glutamate 94 and the cysteinylglycine dipeptide, which is degraded by dipeptidases such as aminopeptidase N (APN), thereby releasing cysteine and glycine
Given the relatively small sample size, the study may have been underpowered to detect modest but biologically meaningful changes
