Thermodynamics of the hydrolysis of sucrose.
A thermodynamic investigation of the hydrolysis of sucrose to fructose and glucose has been performed using microcalorimetry and high-pressure liquid chromatography. The calorimetric measurements were carried out over the temperature range 298-316 K and in sodium acetate buffer (0.1 M, pH 5.65). Enthalpy and heat capacity changes were obtained for the hydrolysis of aqueous sucrose (process A): ...
متن کاملElimination of sucrose transport and hydrolysis in Saccharomyces cerevisiae: a platform strain for engineering sucrose metabolism
Many relevant options to improve efficacy and kinetics of sucrose metabolism in Saccharomyces cerevisiae and, thereby, the economics of sucrose-based processes remain to be investigated. An essential first step is to identify all native sucrose-hydrolysing enzymes and sucrose transporters in this yeast, including those that can be activated by suppressor mutations in sucrose-negative strains. A...
متن کاملIntestinal Absorption of Sucrose in Man: the Site of Hydrolysis and Absorption.
Sucrose, unlike the other common disaccharides, maltose and lactose, has been reported to be absorbed poorly from jejunum in man. Using a single-lumen tube technique and giving a carbohydrate-protein-fat meal with a single disaccharide as the source of carbohydrate, Dahlqvist and Borgstr6m (1) reported efficient absorption of lactose and maltose from human jejunum but minimal absorption of sucr...
متن کاملIntestinal absorption of sucrose in man: interrelation of hydrolysis and monosaccharide product absorption.
Disaccharides are hydrolyzed by their specific enzymes present in the intestinal mucosa (1-3). Although some current textbooks still state that these enzymes are secreted into the intestinal lumen (4-7), the concentrations of monosaccharide products free in intestinal contents during disaccharide absorption in vitro (8-10) have been found insufficient to support the concept of intraluminal hydr...
متن کاملPreferential utilization of the glucosyl moiety of sucrose by a cariogenic strain of Streptococcus mutans.
The utilization of sucrose by a cariogenic strain of Streptococcus mutans was studied. The soluble and cell-bound sucrose-dependent, polymer-forming sucrase activities constitutively produced by the bacteria during growth on glucose were measured. About eight times more dextransucrase activity was present than levan-sucrase activity. During various states of growth on sucrose, S. mutans accumul...
