Biomolecules Question 151

Question: The correct statement about the following disaccharide is

Options:

A) Ring (I) is pyranose with $ \alpha $ -glycosidic link

B) Ring (I) is furanose with $ \alpha $ -glycosidic link

C) Ring (II) is furanose with $ \alpha $ -glycosidic link

D) Ring (II) is pyranose with $ \beta $ -glycosidic link

Show Answer

Answer:

Correct Answer: A

Solution:

[a] The disaccharide with ring (I) having 6 members and hence is a pyranose and the ring (II) has 5 members and hence is a furanose, $ C_1 $ or ring (I) has an $ \alpha $ -glycosidic linkage.
