Trehalose, also known as mycose, is a disaccharide found in certain mushrooms. It is composed of two a-D-glucose linked in a aa(1à1) glycosidic bond. Using Haworth projection, draw the structure of trehalose. Indicate whether it is reducing or non-reducing.

Kindly answer question a & b

Mm.39.

(iii) Draw a structural diagram of a hydrogen bond between β-D-glucose and the side chain of any polar residue in a protein. (iv) Name the type of bond that can occur between the axial hydrogens of glucose and the indole ring of tryptophan. Draw a structural diagram of this bond. (v) Comment on the polar / apolar nature of the bond in part (iv) and explain why this type of interaction is prevalent in protein-sugar complexes.   Answer (iii) to (v) please.
