Reactions of phenolic compounds – a bottomless pit?
Prof. Andreas Schieber, University of Bonn, Bonn, Germany will give an introductory talk entitled "Reactions of phenolic compounds – a bottomless pit?".
Phenolic compounds are subject to a plethora of enzymatic and non-enzymatic reactions, which may tremendously alter their chemical, physical, and physiological properties. The oxidation of o-diphenols leads to the formation of quinones, which are electron-deficient compounds that may readily react with nucleophiles, such as thiol or amino groups. At the same time, the quinones may oxidize other phenols including anthocyanins through various mechanisms.
Despite the importance of reactions in plant physiology, food technology, nutrition and toxicology, and an increase in relevant studies during the past two decades, our understanding of the conversions of phenolic compounds is still limited, which is due, among others, to the large chemical heterogeneity of this class of secondary plant metabolites. The presentation will provide an overview of the reactions of phenolics in general and subsequently describe the behavior of quinones and the resulting conversion products in more detail.
