Oxidation of acetaldehyde by Acetobacter suboxydans.
Acetobacter suboxydans has a powerful system for the oxidation of ethanol to acetic acid, as might be expected from the fact that the acetic acid bacteria have long been used for the commercial production of vinegar. Alcohol dehydrogenase in soluble extracts has been found to be DPlSspecific1 (1). It has now been observed that either TPN or DPN can be used as coenzyme for the oxidation of aceta...
متن کاملThe Gas Phase Oxidation of Acetaldehyde Reaction Mechanism and Kinetics
The mechanism of the low temperature oxidation of gaseous acetaldehyde was investigated in the temperature range of 1 50-400?°C. The minor, intermediate and major products were identified and measured quantitatively by sampling directly into the ionization chamber of an MS10-C2 mass spectrometer from the reactor. The formation of H2O, CO, CO2, HCOOH, H2, HCHO, CH3COOH and CH3OH as the major pro...
متن کاملKinetics of cytochrome P450 2E1-catalyzed oxidation of ethanol to acetic acid via acetaldehyde.
The P450 2E1-catalyzed oxidation of ethanol to acetaldehyde is characterized by a kinetic deuterium isotope effect that increases K(m) with no effect on k(cat), and rate-limiting product release has been proposed to account for the lack of an isotope effect on k(cat) (Bell, L. C., and Guengerich, F. P. (1997) J. Biol. Chem. 272, 29643-29651). Acetaldehyde is also a substrate for P450 2E1 oxidat...
متن کاملImpaired acetaldehyde oxidation in alcoholics.
High blood acetaldehyde levels in alcoholics after ethanol ingestion are due to reduced acetaldehyde oxidation rather than to an increased rate of its formation from ethanol. This is associated with low hepatic acetaldehyde dehydrogenase activity in alcoholic subjects and may represent a specific abnormality in them.
متن کاملThe Kinetics of the Oxidation of Acetaldehyde by Acid Permanganate
The kinetics of the oxidation of aceltaldehyde by acid permanganate has been studied. The reaction is of first order with respect to the aldehyde, the oxidant and hydrogen ion individually. The oxidation does not induce polymerisation of acrylonitrile and show a kinetic isotope effect (&H/AD = 6.1). The activation parameters for the oxidation and enolisation reactions have been evaluated. The r...
