- Glucopyranose are linked by 1 \(\rightarrow\) 4 \(\beta\) glycosidic bonds
- It has branching to a large extent
- It constitutes about 80% starch
- It is water soluble
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding amylose.
Amylose is a type of starch made up of glucose units connected by \(\alpha\)-1,4 glycosidic bonds. It is a linear polysaccharide and is water soluble due to its structure.
Step 2: Analyzing the options.
(A) Glucopyranose are linked by 1 \(\rightarrow\) 4 \(\beta\) glycosidic bonds: Incorrect. Amylose is linked by \(\alpha\)-1,4 glycosidic bonds, not \(\beta\).
(B) It has branching to a large extent: Incorrect. Amylose is a linear polymer with minimal branching.
(C) It constitutes about 80% starch: Incorrect. Amylose constitutes about 20-30% of starch, not 80%.
(D) It is water soluble: Correct. Amylose is soluble in water because of its linear structure and ability to form hydrogen bonds with water molecules.
Step 3: Conclusion.
The correct answer is (D) It is water soluble.
