Conversion of d-psicose to allitol by Enterobacter agglomerans strain 221e
Journal of Fermentation and Bioengineering, 1995Abstract Enterobacter agglomerans strain 221e transformed d -psicose to allitol at a faster rate in the presence of d -glucose in the reaction mixture when the entrance of oxygen was restricted. Cells grown on glycerol were found to be suitable for the transformation reaction.

The synthesis of D-psicose derivatives using recent oxidative procedures
Journal of the Chemical Society C: Organic, 1967The oxidation of authentic 1,2,:4,5-di-O-cyclohexylidene-D-fructopyranose and of 1,2:4,5-di-O-isopropylidene-D-fructopyranose with dimethyl sulphoxide–acetic anhydride yields 1,2:4,5-di-O-cyclohexylidene-D-erythro-hex-3-ulopyranose and 1,2:4,5-di-O-isopropylidene-D-erythro-hex-3-ulopyranose, respectively.

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 method from D-psicose to allitol based on a computational design strategy.

[Research progress of D-psicose: function and its biosynthesis].
Sheng wu gong cheng xue bao = Chinese journal of biotechnology, 2019As the morbidity of metabolic syndrome like obesity and diabetes increases rapidly worldwide, the issue of nutrition (functional food) and health has drawn more attention. D-psicose, a rare natural ketohexose, has become a hot topic in functional food and health-care field because of its hypoglycemic and hypolipidemic function with good sweetness. This

Effects of Low Calorie Sweetener D‐psicose on Lipid Metabolism in Rats
The FASEB Journal, 2017This study aimed to investigate the effect of new generation low calorie sweetener D‐psicose on body weight management and lipid metabolism of rats compared with other traditional dietary carbohydrates. Five groups of Wistar rats were administrated with diets containing 5% of glucose, fructose, cellulose and D‐psicose for 4 weeks, respectively.

Diisopropylidene acetals of D-allose and D-ribo-hexulose (D-psicose)
Carbohydrate Research, 1970Abstract Acetonation of D -allose in the presence of sulfuric acid gives 2,3:5,6-di- O -isopropylidene-β- D -allofuranose ( 4 ) in good yield. Oxidation of 4 with methyl sulfoxide and acetic anhydride gave 2,3:5,6-di- O -isopropylidene- D -allono-1,4-lactone (7). Compound 4 was also obtained from 1,2:5,6-di- O isopropylidene-α- D -allofuranose (
