Question

Amylose is a water-soluble part of starch. What is the percentage solubility of it?

• A. 20 to 30%
• B. 15 to 20%
• C. 30 to 60%
• D. 50 to 70%

Hint:

Amylose's solubility in water is due to its helical structure, which allows it to interact with water molecules.

Answer 1

The Correct Option is A

Amylose is the soluble part of starch. It is a polysaccharide that dissolves in water to some extent, with solubility typically in the range of 20 to 30%.
Step 1: Evaluate the solubility range.
Amylose has a solubility between 20 to 30% in water, which is consistent with the nature of this polysaccharide.
Step 2: Conclusion.
Thus, the correct answer is that amylose has a solubility of 20 to 30%.
