Free-radicals are atoms or molecules containing unpaired electrons. Damage occurs when a free radical encounters another molecule and seeks to find another electron to pair its unpaired electron, in turn causing the new chain to “borrow” from another, damaging all molecules in it in the process causing cells in the body to become dysfunctional especially if the molecules are in a strand of DNA, which can become cross-linked, leading to various effects of aging, especially cancer.
