WebPhospholipid hydroperoxide glutathione peroxidase (PhGPx or GPx-4) is a unique selenium-dependent antioxidant enzyme that reduces membrane-bound phospholipid hydroperoxides (PLOOHs), Scheme 1. [1,2]The human PhGPx gene encodes a cytosolic (S-PhGPx) and mitochondrial (L-PhGPx) form of the protein. WebOct 1, 2008 · We previously confirmed that significantly higher levels of peroxidized phospholipids (i.e., phospholipid hydroperoxides [PLOOHs]) 1 are accumulated in red blood cells (RBCs) of dementia patients [7]. Compounds that can minimize such accumulation may be used therapeutically as effective drugs or functional foods to prevent the disease.
