WebThe human body synthesizes lipids in the liver. Butter, cheese, ghee oil, and whole milk are the sources that are rich in lipids. Lipid peroxidation is a process that is metabolic in nature and causes oxidative deterioration of the lipids. This deterioration of lipid is caused due to its reaction with oxygen-related elements. Weblow rate of lipid peroxidation and low cyto- chrome P-450-mediated activity is associated with an increased rate of cell division. In the liver, normally high in lipid peroxidation ac- tivity, the rate is much lower at times of high cell division, e.g., in fetal and neonatal liver (5). Lipid peroxidation activity has been
