Glucose, structure

Glucose on oxidation gives saccharic acid and on the basis of D-glucose structure, XIV would be D and XV, L on the account of the bottom asymmetric carbon atom. But if XV is rotated in the plane of paper through 180° if becomes exactly identical with XIV. Dispute like this and tartaric acid have raised great interest in improving the system of nomenclature. 

Click on the Frame button and open a second large frame in the Preview window. Double click the left button on the mouse to open the dialog box and click on Read NMR-File... to read in the normal C spectrum of glucose D NMRDATA GLUCOSE 1D C GC 001999.1R. Adjust its size and set the various plot options for this spectrum. Finally readjust the sizes of both windows for the best layout. Open two additional windows and read in the previously saved parameter textfile and the glucose structural formula respectively. Use the Preview Zoom function to inspect the individual... 

Subsequently, the first example of an unsubstituted D-glucose structure having a ring-phosphorus atom was prepared64,85 in improved yield by a modification of the same scheme.

The structures of monsaccharides have been successfully studied by using infrared spectroscopy. For example, this technique can be used to clarify the structure of the simple sugar, glucose. Although glucose exists almost entirely in the cyclic form, in solution it appears to be ih-equilibrium with a minute amount of its non-cyclic structure. Figtire. 6.6a shows these glucose structures.
