Chemistry - Biomolecules Question with Solution | TestHub

Question Explanation:

The question asks to identify the correct statement regarding the ring type and glycosidic linkage present in the given disaccharide.

Concept:

This problem is based on the structure of disaccharides , including pyranose/furanose rings and the α / β nature of glycosidic bonds .

Solution:

Ring (a) contains six members , hence it is a pyranose ring .

The anomeric oxygen linkage from ring (a) is oriented downward , which corresponds to an α-glycosidic configuration .
