Draw the Haworth structure for alpha and beta-D-Arabinose.
Draw the Haworth projections (cyclic forms) of L form along with alpha and beta of each of the following: Glucose (glucopyranose), Mannose (mannopyranose), Galactose (galactopyranose), Fructose, Fructofuranose, Fructopyranose
Use the Haworth projection to draw D-ribose in the beta-furanose and alpha-pyranose forms.
Draw the structure of the polysaccharide alpha-D-Glucopyranosyl- 1-> 3- beta-D-mannopyranosyl – 1->6 - alpha-D-fructopyranose in the chair and Haworth configuration, showing the appropriate glycosidic linkages. Does this polysaccharide have free anomeric hydroxyl groups? If so, circle them in the structure you have drawn.
