Answer 1

AnsA. Acetal

The reaction between hemiacetal and alcohol produces acetal. Hemiacetal is half acetal so, when it reacts with alcohol forms complete acetal.

C. $\alpha$ -1, 4 ;$\alpha$-1, 6

In glycogen, the linear chains are formed by

$\alpha$-1, 4 linkages and branches by $\alpha$ -1, 6 linkages.

D. 2

In $\beta$ $\beta$ 1,1 linkage, two anomeric carbon atoms are linked to one another, hence this linkage has 2 anomeric carbon.

E. Furanose, pyranose

Five membered carbohydrate is called furanose while six nembered is called pyranose.
