Recently, increasingly attentions have been paid to the electro-oxidation of ethanol in alkaline media in the context of using ethanol as a fuel in anion-exchange membrane fuel cell. Alkaline media presents several advantages compared to acidic media. It has been found that the electrocatalytic activity for etanol oxidation in alkaline media is much higher than that in acidic media [1]. Further...

A series of experiments was performed to test the proposal of others that the oxidation of ethanol to acetate is NADflinked, and that, when transferred into the mitochondria, the cytoplasmic reducing equivalents produced during ethanol oxidation inhibit the oxidation of glucogenic precursors required for the formation of P-enolpyruvate. Particulate-free dialyzed extracts of rabbit livers oxidiz...

A hepatic microsomal ethanol-oxidizing system is described both in men and rats. It is distinguished from alcohol dehydrogenase by its subcellular localization (cytosol for alcohol dehydrogenase, microsomes for this system), its pH optimum (physiological pH versus pH 10 to 11 for alcohol dehydrogenase), and its cofactor requirements (NADPH versus NAD+ for alcohol dehydrogenase). It also require...

AIM The examination of the possibility of ethanol oxidation in the brain in vivo and the evaluation of the enzyme catalase in this process. METHODS We anesthetized rats and perfused the brain with ethanol solutions through the lateral ventricle and collected the perfusate from the Cisterna magna. We determined ethanol and acetaldehyde in the perfusate by gas chromatography. RESULTS It was f...

e.g. uricase and d-amino-acid oxidase and their respective substrates, in other words systems which react directly with molecular 02 and reduce it to H202. The increased 02 uptake was shown to be due to the secondary oxidation of ethanol to acetaldehyde by H202 formed in the primary oxidation reaction. It was a matter for some surprise to find that this secondary oxidation of ethanol took place...

p59fyn, a protein tyrosine kinase belonging to the src-family, is involved in the regulatory mechanism of acute response to ethanol in the central nervous system. A previous report showed an association between src-family kinase activity and fatty acid oxidation, and it also reported that hepatic free fatty acid levels were low in Fyn-/- mice. We examined, using Fyn-/- mice whether Fyn is also ...

the rate constants and activation parameters are reported for the oxidation of methanol, ethanol, propanol, and isopropanol by 2,2’-bipyridyl chromium peroxide (bpcp) over the temperature range of 35° to 50°c.

SnO2 has been studied intensely for applications to sensors, Li-ion batteries and solar cells. Despite this, comparatively little attention has been paid to the changes in morphology and crystal phase that occur on the metal oxide surface during chemical reactions. This paper reports anaerobic and aerobic ethanol and CO oxidation reactions over SnO2 nanoparticles (NPs), as well as the subsequen...
