The following structure is that of ribose. Is this a furanose or pyranose form? Is it...
Use the Haworth projection to draw D-ribose in the beta-furanose and alpha-pyranose forms.
Consider the following molecule: Circle the anomeric carbon in the following structure and indicate whether it represents the beta or the alpha anomer. Is this sugar a pyranose or a furanose?
Ribose is an important pentose sugar in the structure of nucleic acids. The linear structure for D-ribose is shown below. Use the methods we discussed in class (also in Timberlake) to convert the linear form below into the corresponding. Haworth structure for the beta anomer of D-ribose. Is the cyclic structure an acetal or a hemiacetal?

The
following model is that of an aldopentose. Draw the BETA anomer of
the sugar in its furanose form. Use wedge & dash to indicate
stereochemistry.
0 labels T..(labels ball & stick the beta anomer of the sugar in its furanose form. . Use the wedge/hash, bond tools to indicate stereochemistry . If a group is achiral, do not use wedged or hashed bonds on i . Use the "flat" representation of rings in your drawing.
