- A one \(\alpha\)-D-glucopyranose unit and one \(\beta\)-D-glucopyranose unit with 1-2 glycosidic linkage
- B two \(\alpha\)-D-glucopyranose units with 1-2 glycosidic linkage
- C two \(\beta\)-D-glucopyranose units with 1-4 glycosidic linkage
- D two \(\alpha\)-D-glucopyranose units with 1-4 glycosidic linkage
Answer & Solution
Correct Answer
(D) two \(\alpha\)-D-glucopyranose units with 1-4 glycosidic linkage
Step-by-step Solution
Detailed explanation
