Since redox processes in the cell are highly regulated, the presence of glutathione in the periplasm at such high levels strongly indicates that this molecule also plays a role in the redox homeostasis of the periplasm, similar to its role in the ER (Birk et al., 2013
Now known as the FoyerHalliwellAsada pathway, this sequence of reactions notably links reduction of H 2 O 2 , catalysed by ascorbate peroxidase, to oxidation of NADH or NADPH, catalysed by monodehydroascorbate reductase and glutathione reductase

Maintaining healthy levels of glutathione is therefore important.
Fluorescence imaging of cellular glutathione using a latent rhodamine
As a central antioxidant, glutathione protects cells from the harmful effects of free radicals and supports essential cellular functions, contributing to better overall health and longevity
