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, ...
