EFFECT OF FREE RADICALS

EFFECT OF FREE RADICALS

PTN cross linking

cystine - lysine - methionine - histidine
enzyme inactivation :Sulfa-hydral enzyme

DNA damage

3- Mutations or cell Killing
2- single strand DNA
1- free radical with thymine =Oxidation

Non-peroxidative mito mem damage

Fenton reaction
Xanthene oxidase

lipid peroxidation of Membranes

free radical attach to double bond of mem form : Lipid peroxide
this LIPID peroxide: unstable & Reactive= extensive damage to All membranes
