Free Radical
What is Free Radical?
A free radical is a highly reactive species containing one or more unpaired electrons. Free radicals are produced by homolytic bond cleavage and can participate in chain reactions. In organic chemistry, radical chain reactions are important in polymerisation and combustion. Biologically, reactive oxygen species (free radicals) can damage DNA and proteins, contributing to ageing and disease.
