It catalyzes the reduction of glutathione from the oxidized form of GS-SG, and all other enzymes of the glutathione system use it: 2 NADP + GS-SG 2 NADP + 2 GSH The reduction of oxidized glutathione is carried out with the participation of NADP + reduction systems on the pentose phosphate pathway of glucose-6-phosphate oxidation ("Embden-Meyerhoff shunt"): NADP + + G-6-P NADP + + + 6 phosphogluconate Glutathione transferase catalyzes the reaction: RX + GSH = HX + GS-SG Some forms of glutathione transferases, like glutathione peroxidases, are capable of reducing lipid hydroperoxides to hydroxy acids (LOH) [12]
4a), saturated and monounsaturated CE species were maintained at higher levels in the KO liver relative to the WT liver following chronic EtOH consumption (Fig

The standard treatment includes the use of antiviral treatment (interferon-alfa with ribavirin)
Additionally, certain variants in genes related to antioxidant response, such as the catalase (CAT) gene and the glutathione peroxidase (GPX) gene, have been associated with increased susceptibility to vitiligo.67,69,70 Furthermore, vitiligo has been associated with defective recycling of tetrahydrobiopterin (6BH4), essential for melanin formation, leading to an excess of 7BH4 and inhibition of phenylalanine hydroxylase (PAH)
