WebGSH is critical for protecting the brain from oxidative stress, acting as a free radical scavenger and inhibitor of lipid peroxidation. GSH also participates in the detoxification of hydrogen peroxide by various glutathione peroxidases. WebLipid peroxides are metabolized to malondialdehyde (MDA) and 4-hydroxynonenal (4-HNE). The local increase of MDA and 4-HNE concentration indicates ROS-dependent tissue damage.

WebResults showed that arsenic decreased GSH levels and increased lipid peroxidation in liver, kidney, and heart, with a larger effect at 18.2 mg/kg than at 14.8 mg/kg for lipid peroxidation induction. In the liver of rats treated with arsenic, pretreatment with NAC increased the levels of GSH and decreased lipid peroxidation. WebMay 24, 2024 · Lipid peroxidation during ferroptosis may as well occur in multiple organelles. The vulnerability of each organelle to lipid peroxidation may be different because of differences in lipid compositions, iron storage, GSH level, LOX expression, and GPX4 localization. For example, mitochondria are rich in iron and GPX4.

WebDuring the GPx-catalyzed reaction, GSH is converted to its oxidized disulfide form (GSSG), which has a decreased ability to reduce peroxide. Once oxidized, GSH can be regenerated from GSSG by the enzyme glutathione reductase (GR), using reduced nicotinamide adenine dinucleotide phosphate (NADPH) as the electron donor and reducing equivalents.
