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. WebApr 3, 2024 · Lipid peroxidation refers to the loss of hydrogen atoms by lipids under the action of free radicals or lipid peroxidases, which leads to the oxidation, breaking, and shortening of lipid carbon chains and the production of cytotoxic substances such as lipid free radicals, lipid hydroperoxides, and active aldehydes, resulting in cell damage.
