MCQ

The correct statement about the following disaccharide is

✓
Ring $(a)$ is pyranonse with $\alpha$-glycosidic link
B
Ring $(a)$ is furanonse with $\alpha$-glycosidic link
C
Ring $(b)$ is furanonse with $\alpha$-glycosidic link
D
Ring $(b)$ is pyranonse with $\beta$ - glycosidic link

✓

Answer

Correct option: A.

Ring $(a)$ is pyranonse with $\alpha$-glycosidic link

a
$(A)$ ring $(i)$ is pyranose with $\alpha$-glycosidic link

The six-membered cyclic structure of glucose is called pyranose structure ( $\alpha$ - or $\beta-$ ), in analogy with pyran which is a cyclic organic compound with one oxygen and five carbon atoms in the ring.

Hence, ring $(i)$ is pyranose.

The ring $(i)$ is pyranose with $\alpha$-glycosidic linkage which means the oxide linkage which connects the monosaccharide units in polysaccharide below the plane.
