damage? A free radical is an electrically uncharged atom or group of atoms having an
unpaired electron. Having one unpaired electron makes the molecule unstable;
thus to stabilize, the molecule gives up an electron to another molecule or steals
one. Therefore it is capable of forming injurious chemical bonds with proteins,
lipids, or carbohydrates-key molecules in membranes and nucleic acids. Free
radical damage is not caused by hypoxia, lysosomal enzymes, or transferring
atoms.
