nounChemistry,Biochemistry. an atom or molecule that bears an unpaired electron and is extremely reactive, capable of engaging in rapid chain reactions that destabilize other molecules and generate many more free radicals: in the body, deactivated by antioxidants, uric acid, and certain enzyme activit...
In 1900, Gomberg 3 observed a strong experimental evidence for the formation of triphenylmethyl radical, and it is generally accepted that this is the beginning of the chemistry of free radicals. It took 30 years, however, until the chemistry of free radial chain reactions was understood. Mayo ...
In this lesson, learn what's a free radical and understand the meaning of free radicals. Find free radical examples to understand how free radicals...
New Concepts of Free Radicals in Chemistry and Biology Free radicals are involved in many aspects of our daily lives, but due to their transient nature and high reactivity, many free radicals and free radical precursors prove difficult to study experimentally. The use of computational quantu... ...
DURING recent years it has become increasingly evident that free atoms and radicals, chemically very reactive but physically quite stable, play an important part as intermediates in chemical reactions. Thus the equation of a chemical reaction, as usually
Elementary radical reactions are described in terms of fundamental knowledge of organic chemistry and chemical physics in this valuable reference text. The complex radical processes of nonchain and chain mechanisms, such as dimerization, alkylation, polymerization, telomerization, halogenation pyrolysis, oxid...

(chemistry) an atom or group of atoms that has an electron that is not part of a pair, causing it to take part easily in chemical reactions. Free radicals in the body are thought to be one of the causes of diseases such as cancer. see also antioxidant (1) Take your English to...
