A new isomerization reaction was developed to synthesize rare ketoses. D-tagatose, D-xylulose, and D-ribulose were obtained in the maximum yields of 24%, 38%, and 40%, respectively, from the corresponding aldoses, D-galactose, D-xylose, and D-ribose, by treating the aldoses with 80% (v/v) subcritical aqueous ethanol at 180°C. The maximum productivity of D-tagatose was ca. 80 g/(Lh). Increasing ...
Riboflavinyl glycosides were synthesized enzymatically using amyloglucosidase isolated from Rhizopus mold and βglucosidase from sweet almond to produce more water soluble riboflavinyl derivatives. The reaction conditions were optimized in terms of incubation period, pH, buffer, enzyme and substrate concentrations. With D-glucose, D-galactose, Dmannose, D-ribose, sucrose, maltose and lactose, bo...
HIGHLIGHTS Exercise increases plasma albumin, while reducing ALT and creatinine. Rosehip reduces AST, creatinine, urea, cholesterol, triglyceride. D-galactose ALT, ALP, adjusts the changes induced by on some variables.
With the use of the cytochemical stain for horseradish peroxidase of Graham and Karnovsky (1966. J. Histochem. Cytochem.14:291), conjugates of horseradish peroxidase with ricin, wheat germ agglutinin, and phytohemagglutinin were employed for the morphologic demonstration of d-galactose (ricin), N-acetylglucosamine (wheat germ), and N-acetylgalactosamine (phytohemagglutinin) containing moieties ...
D-Galactose, which did not serve as a growth substrate, was found to induce an L-arabinose isomerase of similar properties to the L-arabinose-induced L-arabinose isomerase. In both cases the pH profiles, pH stability, optimum temperature, heat stability, substrate specificity, metal ion requirements, mobility on polyacrylamide gel electrophoresis, and kinetic properties of the induced isomerase...
Article info: Received: 18 October 2012 Accepted: 28 February 2013 ABSTRACT Water-soluble and acid-soluble pectic polysaccharides with significant immunostimulating activity were isolated from alcohol-insoluble solids (AIS) of leek. Pectic polysaccharides characterized with high anhydrouronic acid content and common pectic sugars – L-arabinose, D-galactose, D-glucose, and Lrhamnose. It was acco...
