"WebDopamine and GSH. The DA metabolism has been closely linked to an alteration in the GSH metabolism of the brain, since injection of DA in the striatum causes a decline in the GSH content in this brain region. This loss of GSH is most likely the consequence of a chemical reaction of the catecholamine DA with GSH, to form 5-glutathionyl dopamine. " - Gsh metabolism
