The hydroxyl radical can damage virtually all types of macromolecules: carbohydrates, nucleic acids , lipids (lipid peroxidation) and amino acids (e.g. conversion of Phe to m-Tyrosine and o-Tyrosine). The hydroxyl radical has a very short in vivo half-life of approximately 10 −9 seconds and a high reactivity. [5]
The hydroxyl radical, Lewis structure shown, contains one unpaired electron. Lewis dot structure of a Hydroxide ion compared to a hydroxyl radical. In chemistry, a radical, also known as a free radical, is an atom, molecule, or ion that has at least one unpaired valence electron.
The amino radical has two characteristic electronic states: The more stable electronic state is 2 B 1, where the unpaired electron is in the p-orbital perpendicular to the plane of the molecule (π type radical). The high energy electronic state, 2 A 1, has the two electrons in the p-orbital and the unpaired electron in the sp 2 orbital (σ ...
Example radical: Structure of Hydrocarboxyl radical, lone electron indicated as single black dot. A radical is a molecule with an odd number of electrons, and is induced in a variety of ways, including ultraviolet radiation. A sun burn is largely due to radical formation from this radiation. The radical-pair, however, is not simply two radicals.
Specific examples include stroke and heart attack. [ citation needed ] In general, the harmful effects of reactive oxygen species on the cell are the damage of DNA or RNA, oxidation of polyunsaturated fatty acids in lipids ( lipid peroxidation ), oxidation of amino acids in proteins, and oxidative deactivation of specific enzymes by oxidation ...

Radical theory is an obsolete scientific theory in chemistry describing the structure of organic compounds.The theory was pioneered by Justus von Liebig, Friedrich Wöhler and Auguste Laurent around 1830 and is not related to the modern understanding of free radicals.
