Alcohol consumption patterns and genotypes determining alcohol tolerance in chilean university students Patrones de consumo y genotipos determinantes de la tolerancia al alcohol: Estudio en estudiantes universitarios de Santiago de Chile
(Sociedad Medica de Santiago, 2015)
© 2015 Sociedad Medica de Santiago. All rights reserved.Background: Alleles involved in inefficient (ADH1B2*2 and ALDH2*2) or efficient (SNP6, ADH4 gene) alcohol metabolism may influence the risk of alcoholism. Alcoholism ...
Colorimetric assay of ethanol using alcohol dehydrogenase from dry baker's yeast
(Elsevier B.V., 2007-02-05)
Alcohol dehydrogenases (ADHs) are oxidoreductases present in animal tissues, plants, and microorganisms. These enzymes attract major scientific interest for the evolutionary perspectives, afforded by their wide occurrence ...
Improvement of the alcohol dehydrogenase from baker's yeast using polymers and salts for alcohol determinations in beverages
(2014)
An alcohol dehydrogenase (ADH) was purified from dry baker’s yeast. This is a key enzyme of the primary short-chain alcohol metabolism in many organisms. In the present study, the obtained enzymatic preparation of baker’s ...
Improvement of the stability of the alcohol dehydrogenase from baker's yeast using polymers and salts for alcohol determination in beverages
(2014-01-01)
An alcohol dehydrogenase (ADH) was purified from dry baker's yeast. This is a key enzyme of the primary short-chain alcohol metabolism in many organisms. In the present study, the obtained enzymatic preparation of baker's ...
The kinetic behavior of dehydrogenase enzymes in solution and immobilized onto nanostructured carbon platforms
(ElsevierOxford, 2011-12)
This paper describes the kinetic behavior of alcohol (ADH) and aldehyde (AldDH) dehydrogenases in solution and immobilized onto carbon platform via polyamidoamine (PAMAM) dendrimers. All the kinetic constants achieved for ...
Nadh Electrochemical Sensor Coupled by Dehydrogenase Enzymes
(1992-06-01)
A graphite electrode assembled in a flow cell has shown to be a good detector for NADH. Current is linearly dependent on -7-3 concentration in the range 10 -710-3 M without any mediator at the potential applied of 300 mV ...
Dendrimer-assisted immobilization of alcohol dehydrogenase in nanostructured films for biosensing: Ethanol detection using electrical capacitance measurements
(ELSEVIER SCIENCE SA, 2008)
The selective determination of alcohol molecules either in aqueous solutions or in vapor phase is of great importance for several technological areas. In the last years, a number of researchers have reported the fabrication ...
Alcohol dehydrogenase activities and ethanol tolerance in Anastrepha (Diptera, Tephritidae) fruit-fly species and their hybrids
(Sociedade Brasileira de Genética, 2009)
The ADH (alcohol dehydrogenase) system is one of the earliest known models of molecular evolution, and is still the most studied in Drosophila. Herein, we studied this model in the genus Anastrepha (Diptera, Tephritidae). ...
Exploiting the enzymatic machinery of Arthrobacter atrocyaneus for oxidative kinetic resolution of secondary alcohols
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
We evaluated Arthrobacter atrocyaneus (R1AF57) as producer of oxidoreductases for oxidative kinetic resolution of racemic secondary alcohols via oxidation reaction. This bacterium was isolated from Amazon soil samples using ...
Use of different carbon sources in cultivation of baker's yeast for production of glycerol-3-phosphate dehydrogenase
(2013-03-07)
The physiological state of yeast cells changes during culture growth as a consequence of environmental changes (nutrient limitations, pH and metabolic products). Cultures that grow exponentially are heterogeneous cell ...
