1 Explain the meaning of the term mutarotation.
2 Draw the structure of a disaccharide made up of two D-glucose
units. The glycosidic bond is
α-1,6-glycosidic bond.
3 Trehalose is a disaccharide that can be obtained from fungi,
sea urchins and insects. Acid hydrolysis of
trehalose yields only D-glucose. Trehalose is
hydrolysed by α-glucosidase and not by β-glucosidase
enzymes. Methylation of trehalose followed by
hydrolysis yields two molar equivalents of
2,3,4,6-tetra-O-methyl-D-glucopyranose.
From the following experimental data,...
