| A free radical is an energetically unbalanced molecule, composed of an
unpaired electron, that "steals" an electron from another
molecule to restore its balance. Free radicals result naturally when
cell molecules react with oxygen (oxidation) but, with a heavy toxic
load or existing antioxidant deficiencies, uncontrolled free-radical
production occurs. Unchecked, free radicals can cause tissue damage
throughout the body; free-radical damage underlies all degenerative
diseases. Antioxidants such as vitamins A, C, and E curtail free-radical
activity. |
