FREE RADICALS

Domain	Definition
Health	Highly reactive molecules with an unsatisfied electron valence pair. Free radicals are produced in both normal and pathological processes. They are proven or suspected agents of tissue damage in a wide variety of circumstances including radiation, damage from environment chemicals, and aging. Natural and pharmacological prevention of free radical damage is being actively investigated. (references)
Physics	Compounds that contain at least one unpaired electron in place of the more normal and more stable bond consisting of shared electrons. Source: European Union. (references)
Science	Atomic or molecular species with unpaired electrons or an otherwise open shell configuration, usually very reactive. Specific to atmospheric chemistry, free radicals are: short-lived, highly reactive, intermediate species produced by dissociation of the source molecules by solar ultraviolet radiation or by reactions with other stratospheric constituents. Free radicals are the key to intermediate species in many important stratosphericchain reactions in which an ozone molecule is destroyed and the radical is regenerated. See ozone. (references)
