Several lipid molecules containing double bond(s) can be peroxidized under appropriate conditions. The mechanisms inducing lipid peroxidation are complex but are similar for the majority of these molecules.
Unsaturated fatty acids, free or esterified, are the best studied but cholesterol oxidation appears also to be intensely explored.
The primary products of lipid peroxidation being different, you will find below:
– how are peroxidized fatty acids ?
– how is peroxidized cholesterol ?
