Type: MCQ-conceptual-Medium-Class 12
Amylopectin is
A
Soluble in H₂O and have α-1-4 and α-1,6 glycosidic bond
B
Insoluble in H₂O and have α-1-4 and α-1,6 glycosidic bond
C
Soluble in H₂O and have α-1,6 glycosidic bond
D
Soluble in H₂O and have α-1-4 glycosidic bond
Correct Answer
Option A
Detailed Explanation
Amylopectin is a highly branched polysaccharide found in plants, characterized by its solubility in H₂O and its structure, which includes both α-1,4 and α-1,6 glycosidic bonds. The α-1,4 bonds form linear chains, while the α-1,6 bonds create branching points, contributing to its solubility. Option B is incorrect because amylopectin is soluble in water, while options C and D fail to acknowledge the presence of both types of glycosidic bonds, which are essential for its structural properties.
