Abstract

The reversible oxidation of dihydroxy arenes to the respective quinones is a two-electron process with the intermediate formation of the radical form of semiquinones. The redox systems quinone/diphenol (or quinol) are widely present in nature; they participate in electron transfer chains of eukaryotic cells and bacteria, and are involved in the antioxidant defenses of the cell, as well. This article summarizes the chemical and functional characteristics of some biological naphtho- and benzo-quinones such as vitamin K and Coenzyme Q.
