Question

Given the following disaccharide:

Chemical structure of β-sucrose and β-maltose disaccharides with their monosaccharide units.

(i) When the given disaccharide undergoes hydrolysis, determine the two monosaccharide units produced.

(ii) Determine the type of glycosidic bond that holds the disaccharide together.

(iii) Determine the name of the disaccharide and if it is α or ß.

Accepted Answer

Monosaccharides: D-glucose and D-fructose

Glycosidic bond: α(1→2)β

Disaccharide name: β-sucrose

Answer

Monosaccharides: D-glucose and D-galactose

Glycosidic bond: β(1→4)

Disaccharide name: β-maltose

Answer

Monosaccharides: D-glucose and D-glucose

Glycosidic bond: α(1→4)

Disaccharide name: α-lactose

Answer

Monosaccharides: D-galactose and D-fructose

Glycosidic bond: β(2→6)

Disaccharide name: β-sucrose
