MBBS QUESTION #10317
Question 1
Oxidative damage to membrane polyunsaturated fatty acids, driven by free radicals and implicated in aging, atherosclerosis, and tissue injury, is termed:
  • Saponification
  • Lipid peroxidation✔️
  • Esterification
  • Beta-oxidation
Correct Answer Explanation
Lipid peroxidation is a chain-reaction process in which free radicals abstract hydrogen atoms from unsaturated fatty acid side chains, generating reactive lipid peroxides that damage membrane integrity; antioxidants such as vitamin E help limit this process.
