Concept explainers
Interpretation:
The causes of free radical and the method that can be done to prevent free radicals needs to be explained.
Concept introduction:
A free radical can be described as any molecular species that holds an unpaired electron. The presence of an unpaired electron contributes to certain common properties which most radicals share. Many radicals are extremely reactive and unstable.
Answer to Problem 130A
Antioxidants are substances that reduce the effects of free radicals, or avoid them. They give an electron to free radicals, reducing their reactivity. They can give an electron to free radicals without themselves being reactive.
Explanation of Solution
The cells of the human body interact with oxygen via a process which is termed as oxidation. The reaction with oxygen is good thing and it facilitates the cell life-cycle. However, some of the cells get damaged in this process and produced free radicals.
Free radicals are unstable and they take electrons from others and damage chemicals and cells within the body. They not only damage the cells, they damage the DNA within the cell which causes several diseases.
Antioxidants are used to prevent the damage that is caused due to free radicals formation inside the body. They destroy the free radicals before damaging the cells and DNA.
Free radicals are chemically active. Inside our body it breaks cells over time. When the body gets older it loses its capacity to combat the free radicals damage. The result is more free radicals, more oxidative stress, and more cell damage, leading to neurodegenerative disorders and "normal" aging.
