Glucose structural formula

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...

If all the oxygen containing groups are reduced, n-hexane results. This test helps establish that the glucose molecule has a chain structure. One representation of the structural formula of glucose, C6Hi206, is... 

Draw a structural formula for the fructose molecule (remember that fructose is an isomer of glucose). Explain why fructose cannot be oxidized to a six-carbon acid. 

Aldose-ketose isomerism Fructose has the same molecular formula as glucose but differs in its structural formula, since there is a potential keto group in position 2, the anomeric carbon of fmctose (Figures 13 and 13-7), whereas there is a potential aldehyde group in position 1, the anomeric carbon of glucose (Figures 13-2 and 13-6). 

Set up a layout including a spectrum, a textfile and a graphic file with the structural formula of glucose and try to copy this layout via the clipboard into your word processor program, e.g. WORD for WINDOWS. 

From the Display pull-down menu choose the Window option and create an additional window within the 2D plot to include the structural formula of glucose. Start a parallel ID WIN-NMR session and load the structure file D NMRDATA GLUCOSE GLUCOSE.WMF) into the ID WIN-NMR Preview window. Copy it into the clipboard with the Copy command in the Edit pulldown menu of ID WIN-NMR. Return to 2D WIN-NMR, activate the additional window and choose the Paste option in the Output pull-down menu. Move the mouse cursor into the additional window and initialize the transfer from the clipboard by clicking the left mouse button. Resize this window if necessary. 

Start 1D WIN-NMR, enter the Preview window and use the Frame option to open a frame for the 2D layout copied into the clipboard in the previous Check it. With the cursor positioned within the frame double click on the left mouse button to open the dialog box. Click on Paste and then OK to Import the 2D layout. Double click the left mouse button and in the Metafile Options dialog box adjust x-Factor and y-Factor to position the 2D layout correctly within the frame. Open additional frames to accommodate the entire 1D C spectrum D. NMRDATA GLUCOSE 1D C GC 001999.1 R) and the structural formula (Fig. 4.33). Arrange and resize these frames for the best representation. Use additional graphical elements (Lines, Rectangle) available within the Preview window of 1D WIN-NMR for assignment purposes. Set up your output device and plot the layout. 

Open an additional window within the 2D spectrum and include an expansion of a cross peak. Use the Stacked display mode to display this cross peak within this additional window, whereas the Contour display mode remains still active for the main window. Include the structural formula of peracetylated glucose if desired and plot the spectrum according to your preferred layout ideas. 

Relationship between Energy Release and the Oxidation State of Carbon A eukaryotic cell can use glucose (C6Hi206) and hexanoic acid (C6H1402) as fuels for cellular respiration. On the basis of their structural formulas, which substance releases more energy per gram on complete combustion to C02 and H20 ... 

Describe, using chemical structural formulas, the reactions involved in the breakdown of glycogen to glucose 1-phosphate and the synthesis of glycogen from glucose 1-phosphate. 

Order the following substances from the least to most oxidized carbon Formaldehyde, carbon dioxide, methane, formic acid, methanol. Use the open-chain form of glucose and the structural formula for decanoic acid and this scheme to determine the aver-...

Therapeutic Function Sugar supplement Chemical Name 4-O-a-Glucopyranosyl-D-glucose Common Name -Structural Formula ... 

The structural formula of glucose contains a ring having six atoms (C5O, pyranose form) and an aldehyde group (aldoses). However, the structural formula of fructose contains a ring containing five atoms (C4O, furanose form) and a ketone group (ketoses) ... 

The structural formula of sucrose contains two units of monosaccharide (glucose and fructose) joined t( ether by an atom of oxygen, a glycoside link, from carbon 1 of one unit (glucose) to an OH of the other unit (fructose). 

If we examine the structural formula we have drawn for glucose, we see that it contains four chiral centers (marked by asterisks) ... 

The structural formula we have drawn to represent (+)-glucose so far could actually represent any of the 16 aldohexoses. Only when we have specified the configuration about each of the chiral centers will we have the structural formula that applies only to (+)-glucose itself. Before we can discuss the brilliant way in which the configuration of (+)-glucose was worked out, we must first learn a little more about the chemistry of monosaccharides.
