Step 1
  1. a) Trehalose is a nonreducing sugar with chemical formula α-d-glucopyranosyl α-d-glucopyranoside. It has two d-glucose residues linked together by the 1,1-glycosidic bond. Trehalose hydrolysis in presence of trehalase gives rise to the two equivalents of D-glucose as depicted on the whiteboard.
