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.

PLEASE NAME!! OWL is VERY specific on the names. I have very
limited attempts for this question. All of these pictures are the
same two molecules. Letter A in the last picture corresponds to the

the fischer and haworth projections would look like for the
molecules in question. please indicate D and L as well as
alpha/beta (for the second structure). Thank you!
