Metabolite Identification
Common Name2-hydroxy-1,4-benzoquinone
Description2-hydroxy-1,4-benzoquinone belongs to the class of organic compounds known as p-benzoquinones. These are benzoquinones where the two C=O groups are attached at the 1- and 4-positions, respectively. It is formed by the reaction of 1,4-benzoquinone with hydrogen peroxide and is a byproduct of the metabolism of phenols, such as 1,2,4-benzenetriol. 2-hydroxy-1,4-benzoquinone is an extremely weak basic (essentially neutral) compound (based on its pKa). The IUPAC name is 2-hydroxycyclohexa-2,5-diene-1,4-dione. It tends to dimerize spontaneously by peroxo bridges. The enzyme 2-hydroxy-1,4-benzoquinone-2-reductase converts it to 1,4-benzoquinone. The compound is often called 2-hydroxy-1,4-benzoquinone, but the "2-" prefix is superfluous since there is no other hydroxy derivative of 1,4-benzoquinone. The enzyme 1,2,4-benzenetriol dehydrogenase catalyzes the conversion of 1,2,4-benzenetriol to 2-hydroxy-1,4-benzoquinone, and the enzyme hydroxybenzoquinone reductase catalyzes the reverse reaction. It is one of three hydroxybenzoquinone isomers and one of the simplest hydroxyquinones. Hydroxy-1,4-benzoquinone, also called hydroxy-para-benzoquinone, is an organic compound with formula C6H4O3, formally derived from 1,4-Benzoquinone by replacing one hydrogen atom with a hydroxyl (OH) group.
