Oxidoreduction between Cycloalkanols and Cycloalkanones in the Cultured Cells of Nicotiana tabacum. Correlation of the Reaction Rate with the 13C NMR Chemical Shift of the Carbonyl Carbon

Abstract
The enzyme system responsible for the oxidoreduction between cycloalkanols and their corresponding cycloalkanones in the cultured cells of Nicotiana tabacum was found to be alcohol dehydrogenase which is similar to the dehydrogenase from tea seeds and horse liver. The rate constants and the equilibrium constants of the oxidoreduction between the cycloalkanols and their corresponding cycloalkanones with this enzyme system were well correlated with the 13C NMR chemical shift of the carbonyl carbon of the oxidation products, i.e., the cycloalkanones.
