However, this relationship is not always one of simple partnership. Under certain conditions, copper(II) alters the concentration of the antioxidant glutathione by forming metal complexes作者：T Ho·2022·被引用次数：39—Copper and glutathione also interact with AD pathogenic proteinsthrough the process of protein glycation, the non-enzymatic binding of carbohydrates to a .... This interaction can lead to the copper(II)-catalyzed oxidation of glutathione, a process that has been extensively studied. For instance, findings suggest that Cu II -Dp44mT catalyzes GSH oxidation faster than Cu II alone, accelerating the production of reactive hydroxyl radicals. This highlights how copper can influence cellular redox balance, and copper may specifically cause oxidative stress by depletion of the antioxidant glutathione.
