Leucine and Ethanol Oxidation

2015
Ethanol is metabolized to acetaldehyde by catalase in the peroxisome, by the microsomal ethanol oxidation system (MEOS) containing cytochrome P-450, which is located in the endoplasmic reticulum, and by the alcohol dehydrogenase (ADH) pathway of cytosol or the soluble fraction of the cell [1, 2]. Among these metabolic processes, ADH is a key enzyme for

Selective Oxidation of Ethanol to Acetaldehyde on Gold

Journal of the American Chemical Society, 2008
We present results from an investigation of the oxidative conversion of ethanol into acetaldehyde on Au(111) employing temperature-programmed desorption (TPD) and molecular beam reactive scattering (MBRS). Results from isotopic experiments show that ethanol initially undergoes O−H bond cleavage (producing ethoxide) followed by selective β−C-H bond (α ...

Enzymatic oxidation of ethanol in the gaseous phase

Biotechnology and Bioengineering, 1989
AbstractThe enzymatic conversion of gaseous substrates represents a novel concept in bioprocessing. A critical parameter in such systems is the water activity, Aw The present article reports the effect of Aw on the catalytic performance of alcohol oxidase acting on ethanol vapors.

Effects of Bezafibrate on Ethanol Oxidation in Rats

Alcoholism: Clinical and Experimental Research, 1996
Bezafibrate is used to lower serum lipid levels in humans. Fibrate derivatives induce an enzyme participating in the β‐oxidation by peroxisomes. We gave ethanol (2 g/kg) orally to bezafibrate‐treated (300 mg/kg) male rats of the Wistar strain. Blood ethanol levels were remarkably lower and ethanol elimination stood at 432.6 mg/kg/hr (control, 336.6 mg ...

Interference by ethanol in the oxidation of CoA esters

Life Sciences, 1965
Abstract It has been shown that certain conditions may arise during the investigation of the oxidation of CoA esters when the presence of ethanol and alcohol dehydrogenase interfere with the detection of specific CoA ester dehydrogenases. These conditions include 1) the presence of alcohol dehydrogenase and the specific dehydrogenase under ...

Ethanol Biosensors and Electrochemical Oxidation of NADH

Analytical Biochemistry, 1998
Comparative studies of the electrochemical oxidation of reduced nicotinamide coenzyme (NADH) at the surfaces of chemically modified graphite paste electrodes (CMEs) are reported. Three different electroactive materials, tetracyanoquinodimethane (TCNQ), tetrathiafulvalene (TTF), and dimethyl ferrocene (dmFc), were used to construct three different ...

Ethanol‐Induced Oxidative Stress in the Liver

Alcoholism: Clinical and Experimental Research, 1996
Oxygen stress is well recognized to be a key step in the pathogenesis of ethanol‐associated liver injury. Ethanol administration induces an increase in lipid peroxidation either by enhancing the production of oxygen‐reactive species and/or by decreasing the level of endogenous antioxidants.

Enzymatic Mechanisms of Ethanol Oxidation in the Brain

Alcoholism: Clinical and Experimental Research, 2006
Background: The exact enzymatic mechanisms of ethanol oxidation in the brain are still unclear. The catalase‐mediated oxidation of ethanol was demonstrated in rat brain using incubation of brain homogenates with catalase inhibitors. The role of the alcohol dehydrogenase (ADH) or cytochrome P450–dependent system in this process is possible, but has not

Acetate and ethanol oxidation by yeast

Irish Journal of Medical Science, 1964
1. Baker’s yeast metabolises acetate under aerobic conditions and the pH rises steadily due to the replacement of acetate by bicarbonate and carbonate anions. 2. Oxidation of acetate anions, to which the cell is passively impermeable, shows a characteristic induction effect not observed with acetic acid or ethanol which penetrate readily.

Impairment of the asialoglycoprotein receptor by ethanol oxidation

Biochemical Pharmacology, 1996
It is well established that ethanol exposure impairs the process of receptor-mediated endocytosis in hepatic cells, although the molecular mechanism(s) and the physiological consequence(s) of this impairment are unclear. Because addressing these mechanistic questions is difficult in vivo, we have developed a recombinant cell line of hepatic origin ...
