What molecule is removed from glucose molecules during the formation of maltose through glycosidic bond formation?

Draw each of the following:

a. β-D-talopyranose

b. α-D-idopyranose  

Predict whether D-altrose exists preferentially as a pyranose or a furanose. (Hint: In the most stable arrangement for a five-membered ring, all the adjacent substituents are trans.)

Without referring to the chapter, draw the chair conformations of

(c) β-D-galactopyranose (the C4 epimer of glucose).

Draw the β-anomer predicted through the cyclization of D-mannose

Which OH groups are in the axial position in each of the following?

a. β-D-idopyranose

b. α-D-allopyranose

The aldaric acid of D-glucose forms two five-membered-ring lactones. Draw their structures.
