Sucrose metabolism is believed to have a central role in promoting sink strength and sucrose storage in the sugarbeet taproot. How sucrose accumulation is increased by sucrose-degrading enzymes, however, is a paradox. To elucidate roles for sucrose-degrading activities in sucrose accumulation, relationships between the intercellular location of sucrose-

The presence of sucrose synthetase and sucrose phosphate synthetase has been demonstrated in two species of green algae: Chlorella vulgaris and Scenedesmus obliquus. Partial purification from crude extracts allowed the determination of the kinetic constants of algae enzymes. They are very similar to the ones reported for enzymes from higher plants.

ChemInform Abstract: Transformation of Sucrose ‐ Reexamination of Octamolar Tosylation of Sucrose.
ChemInform, 1987AbstractOctamolar tosylation of sucrose with p‐toluenesulfonyl (tosyl)chloride has been re‐examined under different conditions to obtain octa‐O‐tosyl sucrose as a single entity. It was observed that tosylation of sucrose with 8 moles of tosyl chloride in pyridine at 0°C, ‐5°C and ‐15°C afforded octa ‐O‐tosyl sucrose, hepta‐O‐tosyl sucrose, hexa‐O‐tosyl

Database of the properties of sucrose, sucrose solution and food
Journal of Food Engineering, 2006Abstract A new program for interactive computing of physical properties of sucrose, sucrose solutions and any other substances by modelling, simulation and balance calculations was developed. The main data source for the database is monograph Sugar Technologists Manual from Bubnik, Z., Kadlec, P., Urban, D., and Bruhns, M.

Sucrose octaacetate (SOA) is a United States National Formulary (NF) monograph compendial material (U.S. Pharmacopeia, 2008), and, as shown in Fig. 1, has eight acetate groups attached to a sucrose moiety. It is a natural product that has been extracted from the seeds of Annona cornifolia (Lima et al., 2011).

Sucrose Feeding at Weaning Alters the Preference for Sucrose in Adolescence
Experimental and Clinical Endocrinology & Diabetes, 2009The present studies were undertaken to examine the hypothesis that sucrose feeding at weaning may alter the preference for sucrose in the adolescence. Chronological changes of hypothalamic dopamine (DA), its metabolite, 3,4-dihydroxy-phenylacetic acid (DOPAC) and norepinephrine (NE) contents were also measured by HPLC.

A one-step enzymatic assay for sucrose with sucrose phosphorylase
Analytical Biochemistry, 1984A one-step, enzymatic assay for sucrose using sucrose phosphorylase is described. Sucrose phosphorylase, which is now commercially available, was isolated from Leuconostoc mesenteroides strain B-1200 and partially purified by ammonium sulfate precipitation.

Studies on biosynthesis of sucrose
Experientia, 1959Du jus de canne a sucre, les auteurs ont extrait un enzyme, le sucrose phosphorylase, qui differe des enzymes tires jusqu'ici dePseudomonas saccharophilia par certaines proprietes caracteristiques. La presente note etudie ces proprietes et donne la determination de leurs constantes physiques.

The role of sucrose and sucrose synthetase in carbohydrate plant metabolism
Molecular and Cellular Biochemistry, 19741. The role of sucrose as a controlling factor of metabolic activities in the plant cell is discussed. 2. The problem of differentially modifying the rates of synthesis and cleavage of sucrose catalyzed by sucrose synthetase was studied using phenylglycosides, sugars, and divalent cations. 3.

Increased reinforcing efficacy of sucrose/ethanol solutions in comparison to sucrose solutions has been previously demonstrated. However, the contribution of the components of the sucrose/ethanol solution is not well defined. The present study used a multiple schedule of reinforcement to evaluate the differential changes in reinforcer presentations as ...
