Lipid peroxides are the primary products of lipid peroxidation, a process where free radicals remove electrons from the lipids in cell membranes, resulting in cell damage. This process often involves polyunsaturated fatty acids, which are highly susceptible to oxidative damage. Lipid peroxides can further decompose into a variety of secondary products, including malondialdehyde (MDA) and 4-hydroxynonenal (HNE), which are often used as biomarkers for oxidative stress.
