EFFECT OF FREE RADICALS

Meer zoals dit

Introductory biology is the study of biomolecules and cellular components that work together to enable the translation of proteins that are the building blocks of living organisms. Through the idea of central dogma and regulation processes that make sure every step of a process is done correctly so that mutation cannot occur, living organisms can produce and live a healthier life.

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
