Effects of ethanol on mitochondrial oxidations
Biochimica et Biophysica Acta (BBA) - General Subjects, 1964Abstract 1. 1. Effects of ethanol on mitochondrial oxidations in vitro have been studied. 2. 2. Ethanol in relatively low concentrations was found to stimulate the O 2 uptake of rat-liver mitochondria with β-hydroxybutyrate as the substrate. With pyruvate, α-ketoglutarate and succinate as substrate ethanol depressed the O 2 uptake. 3.

Microsomal Ethanol-Oxidizing System
Enzyme, 2017Advances in our knowledge of the microsomal metabolism of ethanol enable us to understand a number of complications that develop in the alcoholic. After chronic ethanol consumption, microsomal ethanol-oxidizing system (MEOS) activity increases with an associated rise in microsomal cytochrome P-450, including a form different from that induced by ...

Effect of thyrotoxicosis on ethanol metabolism and on hepatic ethanol oxidation enzymes
Journal of Endocrinological Investigation, 1982The influence and mechanism of action of T4 treatment on ethanol metabolism was investigated by the determination of ethanol elimination in intact rats and by the estimation of alcohol dehydrogenase and the microsomal ethanol oxidizing system activity in isolated rat liver.

Oxidative and non-oxidative metabolism of ethanol by the rabbit lung
Toxicology Letters, 1992Pulmonary ethanol metabolism in the rabbit was investigated in vitro by examining oxidative (alcohol dehydrogenase) and non-oxidative (fatty acid ethyl ester synthase) pathways. Pulmonary alcohol dehydrogenase (ADH) activity was very low when measured at close to normal physiological conditions but increased at higher pH, although it was lower than ...

Selective Oxidation of Ethanol to Acetaldehyde on Gold
Journal of the American Chemical Society, 2008We 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, 1989AbstractThe 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.

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

Effects of Bezafibrate on Ethanol Oxidation in Rats
Alcoholism: Clinical and Experimental Research, 1996Bezafibrate 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, 1965Abstract 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, 1998Comparative 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 ...
