The presence of an unpaired electron results in certain common properties that are shared by most radicals. Many radicals are unstable and highly reactive. Free radicals and other ROS are derived either from normal essential metabolic processes in the human body or from external sources such as exposure to X-rays, ozone, cigarette smoking, air pollutants, and industrial chemicals. Although there are several enzyme systems within the body that disarm free radicals, the principal antioxidants are vitamin E, beta-carotene, vitamin C, and selenium. When these antioxidants neutralize free radicals by donating an electron particle they are left with a small problem..
