if only one chiral carbon atom has different configurations, they are called epimers. D-glucose and D-mannose are C-2 epimers. Therefore, the reaction of the equilibrium mixture of D-glucose and D-fructose obtained by treating D-glucose with dilute alkali is called epimerization. ...

Chemical shifts (listed below in Tables IV and V) are reported in D2O relative to sodium 2,2,3,3-tetradeutero-3-trimethylsilyl propionate as internal standard. Table IV. 1H NMR data (500 MHz in D2O, 25 °C, ppm from internal TSP4-a of β-d-glucosyl-glucoses, cellobiitol, and β...
Furthermore, the order of antioxidant activities for the seven complexes was as follows: altrose/allose–OVAs > talose/galactose–OVAs > gulose–OVA > mannose/glucose–OVAs. This implies that sugar–protein complexes with two sugars known as epimers about C-2 showed a similar antioxidant ...
Since D-glucose and D-mannose are C-2 epimers and in consequence their deoxygenation at C-2 would produce the same compound, the 2-DG should also be considered an analogue of D-mannose [1] (Figure 1). A significant number of halogen-substituted carbohydrates have been synthesized. Some of...
