WebLipid hydroperoxides (LOOHs) are important intermediates generated during peroxidative degeneration of unsaturated lipids in cell membranes and other organized assemblies. Such degeneration typically occurs under conditions of oxidative stress. 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.
