Lipid peroxidation is a complex process and is generally considered to consist of 3 phases: 1) an initiation phase, which involves the formation of free lipid radicals and hydroperoxides as primary reaction products; 2) a propagation phase where hydroperoxides formed are decomposed into secondary peroxidation products; and 3) a termination phase involving the formation of tertiary peroxidation products (Gutteridge, 1995; Yong and McEneny, 2001). As such, the increased and decreased amount of various lipid peroxidation products over time during each of these phases increases the difficulty of accurately measuring and assessing the extent of lipid peroxidation. Therefore, it is essential to understand the disadvantages of different methodologies used to evaluate lipid peroxidation.
