Therefore, we suspect that endogenous dehydrogenases and substrates other than LDH and lactate may be implicated in NADH production, leading to the false ethanol increases.
The papers represent the latest research in aldehyde dehydrogenases (including such topics as unexpected encounters in simulations f the ALDH mechanism and detoxification of chloroacetaldehyde by human class-9 aldehyde dehydrogenase), alcohol dehydrogenases (including functional roles of alcohol dehydrogenases in human ethanol metabolism and the diversity of beta-hydroxyacid dehydrogenases in plants), carbonyl reductases (including life without aldose reductase, lead optimization in the design of aldose reductase inhibitors and characterizations of a number of test animal organs).

Thus, systems and methods are provided for the recombinant expression of secoisolariciresinol dehydrogenases that may be used to facilitate the production, isolation and purification of significant quantities of recombinant secoisolariciresinol dehydrogenase for subsequent use, to obtain expression or enhanced expression of secoisolariciresinol dehydrogenase in plants in order to enhance, or otherwise alter, lignan biosynthesis, or may be employed for the regulation or expression of secoisolariciresinol dehydrogenase.
Based on published reports on retinoic acid metabolism, the model postulated that dietary vitamin A (retinol) is converted first to retinal and then to retinoic acid by alcohol dehydrogenases and, possibly, by cytochrome P450 enzymes.
