CHAPTER 2 Identification The evidence for the structures of the naturally
occurring quinones is given in the succeeding chapters of this book, and this is
necessarily a mixture of the old and the new. Modern investigations rely very
heavily on the interpretation of spectral information whereas older work, going
back to the structural elucidation of alizarin a hundred years ago, was mainly
dependent on the preparation of derivatives and on degradative experiments.

Quinones, hydroquinones, semiquinones and their metabolites are naturally
occurring compounds that serve as wonderful examples for this new paradigm of
interdigitating,-omics. In addition to a role as substrates and products in
metabolism, quinone compounds are intermediates in many pathways of gene
regulation, enzyme protein induction, feedback control, and waste product
elimination. Quinones play a pivotal role in energy metabolism (Peter Mitchell's
proton-motive, ...
