In recent years, the field of radical chemistry has undergone explosive growth. Although its roots lie in organic chemistry, the implications of its findings are having enormous impact in a broad range of disciplines, and we now have evidence for radical involvement in over 100 diseases. As important as this is, however, the subject of radicals and Reactive Oxygen Metabolites (ROMs) is complex and barely touched upon in the curriculum of medical schools. Reactive Oxygen Metabolites brings the subject within the grasp of even those with little preparation in chemistry. From the basic chemistry of radicals through the pathology, the author provides a clear and thorough introduction to ROMs and their importance to human health and disease.
