摘要：

The E-pH diagram has enabled us to obtain the acid-base constant of ubiquinone and the equilibrium potential at pH = 0 for the different couples participating in the process of quinone adsorption on a pyrolytic graphite electrode in aqueous buffered media. The electrochemical behaviour found for ubiquinone may explain in part the in vivo ubiquinone processes. The molecular contour of deoxyribonucleic acid changes the stability of the semiubiquinone intermediate, as shown by chemiluminescence and binding experiments. © 1990.
