Enzyme-catalyzed processes in organic solvents.
Three different lipases (porcine pancreatic, yeast, and mold) can vigorously act as catalysts in a number of nearly anhydrous organic solvents. Various transesterification reactions catalyzed by porcine pancreatic lipase in hexane obey Michaelis-Menten kinetics. The dependence of the catalytic activity of the enzyme in organic media on the pH of the aqueous solution from which it was recovered ...
متن کاملEnzyme-catalyzed decomposition of dibenzoyl peroxide in organic solvents.
Catalytic activity of catalase (CAT, EC 1.11.1.6), immobilized on carbon black NORIT and soot PM-100, with respect to decomposition of dibenzoyl peroxide (BPO) in non-aqueous media (acetonitrile and tetrachloromethane), was investigated with a quantitative UV-spectrophotometrical approach. Progress of the above reaction was controlled by selected kinetic parameters: the apparent Michaelis const...
متن کاملInfluence of occupational exposure to organic solvents on kidney function.
Exposure to nephrotoxic substances may cause renal tubular and glomerular dysfunction. The aim of the paper was to evaluate, based on literature reports, whether occupational exposure to organic solvents entails a risk of renal dysfunction. The results of the studies performed over the last twenty years are contradictory. In workers occupationally exposed to organic solvents, tubular, glomerula...
متن کاملkinetics studies of peroxidase enzyme in the presence of organic solvents ethanol and butanediol
abstract peroxidases are a group of oxidoreductases that are produced by a number of microorganisms and plants, and catalyse the reduction of peroxides. peroxidases are widely used in clinical biochemistry and enzyme immunoassay. horseradish peroxidase isoenzyme c (hrp) is one of the characterized peroxidases. the structure of the enzyme is largely alpha helical. kinetics studies of peroxidase ...
متن کاملChemiluminescence Properties of Peroxyoxalate System in Organic Solvents
Peroxyoxalate system includes an oxalate ester, peroxide and a fluorescer, The energy resulted from the reaction of oxalate ester and peroxide is transferred to fluorescer and cause it to fluorsc. The effect of reactants chemical structure, their concentration, solvent media (polarity and viscosity) and the temperature, on the intensity of the illuminated light with respect to time have bee...
