The structure of sucralose, found in the artificial sweetener Splenda, is shown in the figure. It consists of a chlorinated disaccharide made up of galactose and fructose. In its structure shown, (b) identify the type of glycosidic bond present.

Consider the trisaccharide A, B, C shown in Problem 20.23.

c. State the numbers of the carbon atoms that form glycosidic linkages between monosaccharide A and monosaccharide B.

Look at the open-chain form of D-mannose and draw the two glycosidic products that you expect to obtain by reacting D-mannose with methanol.

For each of the following disaccharides, name the glycosidic bond and draw the monosaccharide units produced by hydrolysis:
