Free radicals are intermediates in many normal and necessary metabolic reactions. Thus, all oxygen-using organisms have had to evolve defensive mechanisms against free radicals: The enzymes catalase and peroxidase break down hydrogen peroxide and other peroxides, superoxide dismutase (called SOD) controls the superoxide free radical, and glutathione peroxidase also controls peroxides. Antioxidants such as vitamins […]

… all diseases may by sure means be prevented or cured, not excepting that of old age, and our lives lengthened at pleasure even beyond the antediluvian standard. —Benjamin Franklin, in a letter to English chemist Joseph Priestley The same molecules that serve us well by keeping us alive and healthy can, if they fail […]
