  Hydroxyl - Encyclopedia, History, Geography and Biography
The term hydroxyl group is used to describe the functional group -OH when it is a substituent in an organic compound.
The hydroxyl radical, ·OH, is the neutral form of the hydroxide ion.
The Hydroxyl radical is often referred to as the "detergent" of the troposphere because it reacts with many pollutants, often acting as the first step to their removal.

 Lecture 33
The hydroxyl radical consists of one oxygen atom and one hydrogen, atom chemically bonded to form a diatomic molecule.
The most common reaction of the hydroxyl radical is called "hydrogen abstraction." In hydrogen abstraction reactions a hydrogen atom from another substance is added to the hydroxyl radical, converting the hydroxyl radical to a water molecule and simultaneously generating a new radical on the substance which lost the hydrogen atom.
Hydroxyl radicals can combine directly with another substance to form a new molecule that includes all the atoms from the two initial molecules.

 Le Magazine, December 1995 - The Dangerous Hydroxyl Radical
The hydroxyl radical is a third generation species of radical which is derived from hydrogen peroxide (HZ02), which, in turn, is derived from the superoxide radical through the action of the enzyme superoxide dismutase.
Hydrogen peroxide is reduced to hydroxyl radicals by the enzymes glutathione peroxidase and catalase in the presence of transition metals such iron or copper.
The fact that melatonin is so much better at scavenging hydroxyl radicals than any other antioxidant is persuasive evidence that melatonin protects us against a wide variety of diseases and that its progressive depletion with advancing age contributes to aging and the diseases and disabilities associated with aging.
