1 ame Key W06-Exam o. Page I. ( points) A disaccharide is cleaved by a β-glycosidase, an enzyme that specifically hydrolyzes a β- glycosidic linkage. When the disaccharide is treated with excess dimethyl sulfate [(C ) S ]/a/ and then hydrolyzed under aqueous acidic conditions at around 90 C, two monosaccharide products are formed:,,-tri--methyl-d-mannopyranose () and,,,6-tetra--methyl-d-galactopyranose (). C C!-D-mannopyranose!-D-galactopyranose () Draw in the box below the structure of the disaccharide. Each of the monosaccharide units should be drawn in the aworth projection formula and the stereochemistry of the anomeric hydroxyl group in the β- form. C C 6 () Draw in the boxes given below the structures of the two methylated monosaccharide products and in their most stable chair conformers. Assume the stereochemistry at the anomeric hydroxyl group to be in the β-form. For : For : C C C C C C C
