Which one is soluble in hot water_____________?
Correct answer: C. Amylose
- A. Starch
- B. Glycogen
- C. Amylose
- D. Amylopectin.
Explanation
Amylose, the mostly unbranched component of starch, can dissolve in hot water and forms a colloidal solution. Students may choose amylopectin because it is also a component of starch, but its extensive branching makes it much less soluble in hot water than amylose.
