How might aging and oxidation be related?

Interpretation Introduction

Interpretation:

The relationship between the aging and oxidation is to be explained.

Concept introduction:

A molecule that contains unpaired electron(s) is called a free radical and radicals are highly reactive and toxic.

Free radicals are generated as a by-product from oxygen catabolism during the oxidative stress.

A free radical can be generated by the cleavage of a weak bond between electrons.

Explanation of Solution

The theory of aging postulates that oxidizing agents are free radicals. A free radical is an atom, molecule, or ion that contains at least one unpaired electron. Free radicals are formed from the oxygen metabolism as a byproduct during oxidative stress. Free radicals are highly reactive and harmful. It will search electrons from a biological molecule (membrane) and oxidize them.

The theory of aging proposes that electrons are extracted from the membranes of the molecule by a free radical, to oxidize the molecule...
