The problem of sucrose utilization has not been sufficiently studied to ascertain whether the disaccharide is used directly, inverted by hydrolysis, or broken down through some other mechanism prior to further metabolism. It is well known that fructose in its free form occurs as a relatively stable six-membered ring compound (pyranose configuration), whereas in the sucrose molecule it is found ...

Aim. Analysis of physiological and biochemical characteristics genetically modified wheat with partially suppressed activity the proline dehydrogenase gene. Methods. Determination (PDH) activity, free L-proline (Pro); carbohydrate content (sucrose fructose). Results. It was established that under conditions water deficit in plants integrated elements forming double-stranded RNA suppressor pdh g...

Abstract Background Altered substrate transport protein expression is central to the effect of insulin resistance on cardiac metabolism. The present study was thus designed investigate comparative effects high fat, sucrose and salt-induced IR fatty acid transporter (FATP) glucose (GLUT4) in rats. Results Rats fed with salt diets developed impaired tolerance ( p > 0.05) hyperinsulinemia < ...

BACKGROUND Chronic unpredictable stress (CUS) can cause behavioral and physiological abnormalities that are important to the prediction of symptoms of depression that may be associated with cerebral glucose metabolic abnormalities. Curcumin showed potential antidepressant effects, but whether or not it can reverse cerebral functional abnormalities and so ameliorate depression remains unknown. ...

Activities of the sucrose-cleaving enzymes, acid and neutral invertase and sucrose synthase, were measured in pods and seeds of developing snap bean (Phaseolus vulguris L.) fruits, and compared with t4C-import, elongation and dry weight accumulation. During the first 10d postanthesis, pods elongated rapidly with pod dry weight increase lagging behind by several days. The temporal patterns of ac...

Sink organs of most plant species are supplied with carbon and energy in the form of sucrose. The channeling of sucrose into sink metabolism requires its cleavage by several isoforms of invertase and sucrose synthase, which are localized in different subcellular compartments. These activities regulate the entry of sucrose into distinct biochemical pathways, such as respiration or biosynthesis o...

Sucrose cleavage is vital to multicellular plants, not only for the allocation of crucial carbon resources but also for the initiation of hexose-based sugar signals in importing structures. Only the invertase and reversible sucrose synthase reactions catalyze known paths of sucrose breakdown in vivo. The regulation of these reactions and its consequences has therefore become a central issue in ...

Sucrose metabolism and the role of sucrose synthase were investigated in the fruit tissues (pericarp, perisperm, and endosperm) of Coffea arabica during development. Acid invertase, sucrose phosphate synthase, and sucrose synthase activities were monitored and compared with the levels of sucrose and reducing sugars. Among these enzymes, sucrose synthase showed the highest activities during the ...

Abstract The colonic epithelium requires continuous renewal by crypt resident intestinal stem cells (ISCs) and transit amplifying (TA) to maintain barrier integrity, especially after inflammatory damage. An important regulator of ISC TA cell function is dietary metabolites which can affect their proliferative capacity. Over the last 150 years, diet high-income countries contains increasing amou...
