What is free radicals？

Free radicals are atoms or groups in the human body that have unpaired electrons.Free radicals are responsible for burning energy, transmitting energy, signal transmission, free radicals in cells, or being controlled and not being chaotic, they are harmless to life, for example, when harmful bacteria invade the human body, White blood cells release free radicals and destroy invaders, which is a beneficial side of free radicals.

However, if there are too many free radicals, it will lose control, destroy other cells, genes, etc., and cause a series of chain-locking reactions, resulting in damage to normal cells and tissues of the human body, causing various diseases.Such diseases as heart disease, Alzheimer’s disease, Parkinson’s disease and tumors; mutations in nucleic acids, induction of cancer, etc.; this is the root cause of human aging and disease.At present, scientists have confirmed that there are more than 60 diseases caused by oxygen free radicals, and indirectly caused more than 2,000 diseases. Almost all diseases are closely related to free radicals.

What is the damage to the human body after the lipids in the cell membrane are oxidized by oxygen radicals?

After the lipids in the cell membrane are oxidized, 1. The cell fluidity is reduced, the cell permeability is increased, 2. The product which is toxic to cells such as malondialdehyde is produced. 3. A variety of active free radicals are generated, and the active free radical attacks the cellular protein to Inactivate them.
