Universal role of quinones in natural and artificial photosynthetic systems: overview from chemical properties to biological importance.

ABSTRACT:

Main conclusion

A comprehensive view of redox properties of quinones has demonstrated how prenylquinonones define the operation of photosynthetic electron transfer in thylakoids. The synthetic quinones play an analogous role in photosynthesis research and biophotovoltaic devices. The para-quinones are an enormous group of small organic molecules assembled from benzoquinone core and two carbonyl groups that may be reduced to hydroxyl groups by accepting two electrons and two protons. Their redox properties depend on types of attached functional groups and are strongly influenced by the surrounding environment. The process of their reduction/oxidation may occur in multiple stages by specific molecular species that differ in electrochemical properties. These properties make quinones v
