Behavior of dextrins towards taka-diastase.
That taka-diastase, when allowed to react under the appropriate conditions, will hydrolyze starch and maltose completely or almost completely to glucose has been known for some time (2, 9). It might, therefore, be expected that dextrins, which are intermediates in the hydrolytic breakdown of starch to maltose, should be similarly susceptible to taka-diastase. Results contrary to this expectatio...
متن کاملA method for the determination of small quantities of mixed reducing sugars and its application to the estimation of the products of hydrolysis of starch by taka-diastase.
PRELIMINARY investigations on the carbohydrates in the developing apple have shown that the concentration of sugars in the fruit is less than 1 % during the first weeks of growth, and further, that the maximum starch concentration reached at any time is only about 2 %. Estimation of these carbohydrates by the usual methods would require the collection of a very large number of apples, especiall...
متن کاملInfluence of Buffer Solution on Tempo-mediated Oxidation
TEMPO-mediated oxidation has been reported to effectively convert C6 primary hydroxyl groups to carboxyl groups for better water-solubility. However, the pH decreases continuously during the oxidation process, and it is therefore difficult to maintain the stability of the reaction. The control of pH at a constant level throughout the oxidation process is a complicated task. The applicability of...
