glutathione pyruvate dehydrogenase Scheme showing the enzymatic reactions that catalyze the Pyruvate Dehydrogenase Complex and TCA

GGT-catalyzed removal of the -glutamyl moiety from glutathione releases a Cys-Gly dipeptide, which undergoes either direct uptake by peptide transporter PEPT2 in some cells or further degradation into free amino acids, Cys and Gly, via extracellular dipeptidases [127,128]

Then, the cluster profiles evolve over the course of selection rounds and applied selection pressure

Through the GABAglutamineglutamate (GGG) cycle, astrocytes convert absorbed glutamate or GABA into glutamine, which is subsequently shuttled back to neurons
