1. a chemical process in which peroxide compounds are formed, especially the oxidation of organic molecules by peroxides or oxygen
Usage: technical; chemistry
2. the degradation of lipids and other biological molecules caused by reaction with peroxides, often associated with cellular damage and aging
Usage: biochemistry; biology

Examples

• Lipid peroxidation is a major cause of cell membrane damage in oxidative stress.
• The peroxidation of unsaturated fats can produce harmful free radicals.
• Antioxidants help prevent peroxidation in biological tissues.
• Industrial peroxidation processes are used to manufacture certain chemicals.
• The study examined how peroxidation contributes to aging at the molecular level.
