Radicals are required for a number of biochemical reactions. Nucleic
acid biosynthesis depends upon free radicals. The immune system
chemical nitric oxide operates by free radical means. Simple metabolism
unavoidably produces radicals as a matter of course. If they were
eliminated, metabolism would cease. The problem is uncontrolled
radicals. Those are damaging.
