When plants are growing in unchallenging conditions, in which GSH-oxidizing compounds are kept relatively low by cellular antioxidant systems, the glutathione redox potential in subcellular compartments such as the cytosol, chloroplast, and mitochondria is maintained at highly reducing values
Despite these advances, several critical challenges continue to impede the practical clinical translation of CQDs [103]
For decades, GPX typically uses glutathione (GSH) as a reducing agent in catalyzing the reduction of H 2 O 2 or organic hydrogen peroxide to water or corresponding alcohols, respectively ( 2 O 2 and rapid reduction by GSH ( 2 O 2 ( A great deal of research on the structure and function of GPX in mammals has helped us understand the essential functions of this class of proteins
First , it is the rate-limiting cofactor for collagen biosynthesis specifically for the hydroxylation of proline and lysine residues that allow the collagen triple helix to form correctly
4.2 Targeting Gln metabolism to inhibit tumor proliferation 4.2.1 Inhibition of Gln uptake Tumor survival and proliferation are heavily dependent on Gln, a hydrophilic amino acid that must be transported into tumor cells by transmembrane proteins, such as SLC1A5, SLC6A14, and SLC38A1/2
