    A review on the role of quinones in renal disorders
    Quinones are electron and proton carriers that play a primary role in the aerobic metabolism of virtually every cell in nature. Most physiological quinones are benzoquinones. They undergo highly regulated redox reactions in the mitochondria, Golgi apparatus,

    Pyrroloquinoline-Quinone Is More Than an Antioxidant: A Vitamin-like Accessory Factor Important in Health and Disease Prevention
    Pyrroloquinoline quinone (PQQ) is associated with biological processes such as mitochondriogenesis, reproduction, growth, and aging. In addition, PQQ attenuates clinically relevant dysfunctions (e.g., those associated with ischemia, inflammation and

    Where do Quinones come from?
    The quinones are found in bacteria, in certain fungi, and in various higher plant forms, but in only a few animals. Those animals in which they do occur—e.g., sea urchins, aphids, lac insects, and certain scale insects—obtain their quinone compounds from the plants they eat.

    Are quinones biologically active?
    A number of studies are reported to cover the chemical reactivity in an attempt to understand quinones as biologically active compounds. Data ranging from normal analytical methods to study quinones derived from plant or biological matrices to the use of labeled compounds are presented.

    Is quinone a carcinogen?
    Quinone is known to cause eye irritation with chronic dust or vapor exposure. Keratitis, corneal ulceration, and discoloration of the conjunctiva may occur. Workers exposed chronically to these compounds may develop a reddish discoloration of the hair. No epidemiological data relevant to the carcinogenicity of quinone are available.

    Does quinone binding and chemistry play a key role in the coupling mechanism?
    Our results suggest that quinone binding and chemistry play a key role in the coupling mechanism of complex I. Complex I (NADH:ubiquinone oxidoreductase) is the first enzyme of the respiratory chain in bacteria and mitochondria.
