Lipid peroxidation is a biochemical process in which reactive oxygen species (ROS) cause oxidative degradation of lipids. This process primarily affects polyunsaturated fatty acids within cell membranes, leading to cell damage and dysfunction. The outcome of lipid peroxidation is the formation of lipid radicals and various secondary products such as malondialdehyde (MDA) and 4-hydroxynonenal (4-HNE).
