Sources of Free Radical Damage

By far, most free radical damage comes from the cell’s own metabolism.

Our cells take the oxygen inspired by the lungs and use it in enzymatic reactions to burn fuel (glucose, fat, or even protein) and create energy.

Each cell uses its energy to perform its own individual function.

Nature did not make us totally efficient in the use of energy, however. Each cell makes extra energy to insure it will be able to perform its function.

As energy is created, radicals (very high-energy molecules) are created.

More are generated than are needed. The extra ones "spin off" into the interior of the cell, combining with whatever structure they strike, damaging that structure.

These extra packets of energy are termed "free radicals" because they are not committed to any particular ongoing biochemical reaction.

Being of very high energy, they combine with whatever they first touch.

Free radical damage can be thought of as a natural consequence of living and breathing in an oxygen-rich environment.
