Chitosan Productivity Enhancement in Rhizopus oryzae YPF-61A by D-Psicose
Journal of Bioscience and Bioengineering, 2003The effect of the rare sugar D-psicose on chitosan production by Rhizopus oryzae was studied. The fungus was not able to utilize D-psicose as a sole source of carbon, either for germination of the spores or for growth of the vegetative cells. In a medium containing a low amount of D-glucose, however, D-psicose supplementation between 5 and 12 g/l ...

Molecular Modification of Ribitol Dehydrogenase and Efficient Catalysis of D-Psicose to Allitol.
Journal of Agricultural and Food ChemistryAllitol has wide applications in fields such as food and pharmaceuticals. To address the limited industrial production of allitol caused by the low catalytic efficiency of native ribitol dehydrogenase (RDH), we developed an efficient biotransformation ...

Effect of d‐psicose substitution on gelatin based soft candies: A TD‐NMR study
Magnetic resonance in chemistry : MRC, 2019Confectionary gels are considered as composite gel systems composed of high amount of sugar and gelling agent such as gelatin or starch. d‐Psicose is classified as a type of rare sugar, which is a C‐3 epimer of fructose and has 70% of the sweetness of ...

Anti-obesity potential of rare sugar d-psicose by regulating lipid metabolism in rats.
Food & Function, 2019d-Psicose is a new-generation sugar substitute with a low calorie count and can still offer the desirable sweetness. The objective of this study was to investigate the antiobesity potential of d-psicose and the possible mechanism using Wistar rats as the

Synthesis and stereochemistry of some derivatives of d-psicose
Carbohydrate Research, 1979Abstract A number of derivatives of the ketohexose d -psicose have been synthesized, comprising examples of acetals, esters, ethers, and glycosides. Among them are precursors of 1-,3-,5-, and 6-mono- O -methyl- d -psicose, including 3- O -methyl-β- d -psicopyranose 4,5-carbonate, the first crystalline representative of the reducing form of the ...

Crystal data of branched-chain derivatives of D-psicose
Journal of Applied Crystallography, 1981Crystal data are reported for six derivatives of 1,2-O-isopropylidene-3-C-(pyridin-2-yl)-β-D-psicopyranose, C14H19NO6, previously studied in solution by NMR spectroscopy. Molecules that differ only by the replacement of H by CH3 on one non-ring oxygen atom, converting an alcohol to an ether molecule, show no similarity in cell dimensions, and have ...

Efficient conversion of allitol to d-psicose by Bacillus pallidus Y25
Journal of Bioscience and Bioengineering, 2007An efficient method for conversion of allitol to D-psicose was achieved by a resting cell reaction of Bacillus pallidus Y25 for the first time. Notably, it was possible to produce D-allose and D-altrose from allitol directly via D-psicose by prolonging the reaction time. This method was applied for the preparation of D-psicose using the extract of Itea
