Cotton embryos from 34 to 54 days after anthesis were analyzed for organic acids, and enzymes associated with organic acid metabolism. During this developmental period, embryos accumulated citrate. Malate synthase activity appeared at 46 days after anthesis and increased rapidly to 54 days. Of other enzymes examined, only citrate synthase activity increased during this period. As isocitrate lya...

Sucrose is the main saccharide used for long-distance transport in plants and plays an essential role energy metabolism; however, there are no analogues real-time imaging live cells. We have optimised a synthetic approach to prepare sucrose including very small (?50 Da or less) Raman tags fructose moiety. Spectroscopic analysis identified alkyne-tagged compound 6 as analogue recognised by endog...

The effects of sucrose stearate at various concentrations (0.1%, 0.2%, and 0.3%, w/v) on the physico-chemical characteristics of ready-to-eat (RTE) Samgyetang were investigated during storage at 25℃ for 12 mon. Over the storage duration, the addition of sucrose stearate had no significant effects on the proximate composition of Samgyetang, including meat, broth, and porridge, or the hardness an...

The cDNA encoding sucrose-fructan 6-fructosyltransferase (6-SFT) from barley (Hordeum vulgare) has been expressed in the methylotrophic yeast Pichia pastoris, using a translational fusion into vector pPICZ alphaC, containing the N-terminal signal sequence of Saccharomyces cerevisiae alpha-factor to allow entry into the secretory pathway. Transformed Pichia produced and secreted a functional 6-S...

Slurries of whey protein concentrate (WPC) or sodium caseinate (Na-CN) mixed with sucrose (36% T.S.) were subjected to microparticulation by a high shear homogenizer operated at 27,000 rpm for 2, 4, and 6 min to facilitate gel formation. After microparticulation treatment, the milk protein and sucrose slurries were evaporated at 85 degrees C for 60 min under a partial vacuum (20 to 45 mm of Hg)...

D-Ins(1,3,4,5)P4 and unnatural L-Ins(1,3,4,5)P4 were prepared in gram-quantities from D- and L-2,6-di-O-benzyl-myo-inositol by a chemical phosphorylation and deprotection step in high yield and purity without extensive purification. The optically pure benzyl derivatives were obtained by enzyme-catalyzed resolution of racemic 2,6-di-O-benzyl-myo-inositol under acyl-transfer conditions in vinyl a...

The present study reveals antimicrobial potentials and phytochemical analysis of A. javanica and L. ustitatissimum. Phytochemical analysis indicated that the tested plants contained a substantial amount of flavonoids, terpenoids and steroids while saponins and tannins were absent in L. ustitatissimum, however, tannins were present in A. javanica. L. ustitatissimum contained maximum total phenol...

A new class of antiandrogen medications, gonadotropin-releasing hormone agonists, offers promise in the treatment of the paraphilias, with substantially less side effects than medroxyprogesterone acetate or cyproterone acetate. This paper reports the results of treatment using a depot suspension of leuprolide acetate on 12 patients with paraphilic disorders or with sexual disorders not otherwis...

12 men and 12 women, classified as carbohydrate-sensitive on the basis of an exaggerated insulin response to a sucrose load, consumed diets containing either 5, 18, or 33% sucrose in a crossover design. The diets simulated the average American diet and consisted of identical natural and processed foods with the exception of a patty. The patty provided the experimental levels of sucrose; the dif...

The aim of this work was to use preparations from germinating seeds of Pisum sativum to determine the apparent equilibrium constant of the reaction catalysed by sucrose-phosphate synthase (EC 2.4.1.14) and to compare this with the mass-action ratio of the reaction in the seeds. The apparent equilibrium constant ranged from 5.3 at 0.25 mM-MgCl2, pH 7.0, to 62 at 10 mM-MgCl2, pH 7.5. The sucrose ...
