Draw the Haworth Projection that would be expected from cyclization of D-Fructose into α-D-Fructofuranose

Draw the following sugar in the α-pyranose form.

Draw the following sugars using Haworth projections:

b. a-d-tagatopyranose

Using the Haworth projection, draw the furanose ring that would form between the C₅ hydroxyl group and the ketone at C₂ for the molecule shown.

Using the Haworth projection, draw the furanose ring that would form between the C₄ hydroxyl group and the aldehyde at C₁ for the molecule shown.

Draw the anomers of d-erythrofuranose.

d-Glucose most often exists as a pyranose, but it can also exist as a furanose. Draw the Haworth projection of a-d-glucofuranose
