Horse liver alcohol dehydrogenase was reacted with glyoxal at different pH values ranging from 6.0 to 9.0. At pH 9.0 the enzyme undergoes a rapid activation over the first minutes of reaction, followed by a decline of activity, which reaches 10% of that of the native enzyme. Chemical analysis of the inactivated enzyme after sodium borohydride reduction(More)
A chemical method for the removal of chromogenic phenolic constituents and carbohydrates of the sunflower meal has been investigated. This method uses a nondenaturing polar solvent formed by n-butanol saturated by diluite HCl and allows the preparation of protein isolate off-colour free. Evaluations on the extractibility of phenols, carbohydrates and(More)
