Free radical


To understand the way that free radicals and anti oxidants interact, I will tell you a bit about cells and molecules.
The human cells body is composed of many different types of cell. Cells are composed of many different types of molecules. Molecules consist of one or more atoms, and each atom is surrounded by electrons. Atom is unstable when it had odd number of electron, and it called free radical.
Free radical is very unstable, so it attacks to the nearest stable molecule, stealing its electron. The attacked molecule loses its electron, becoming a free radical itself. So a chain reaction begins, and finally resulting in the disruption of living cell.
What anti oxidant do?
Anti oxidant neutralize free radical by donating one of its own electrons, ending electron stealing reaction. The anti oxidant doesn’t become free radical by donating an electron.
Where does free radical come from?
They are by product of normal bodily process like breathing, or digesting food. They are also unleashed by external factors including sunlight, cigarette smoking, and air pollution. Exercise increase generation of free radical too, but regular physical exercise enhance the anti oxidant defense system.
