Which of the following is soluble in hot water?
Correct answer: C. Amylose
- A. Starch
- B. Glycogen
- C. Amylose
- D. Amylopectin
Explanation
The correct answer is amylose, as it is the only option that is soluble in hot water. Amylose consists of a linear chain of glucose units connected by α-1,4-glycosidic bonds, allowing it to dissolve by forming hydrogen bonds with water. In contrast, amylopectin and glycogen are highly branched, making them too large and complex to dissolve in hot water. Starch, composed of both amylose and amylopectin, is not completely soluble due to the higher proportion of insoluble amylopectin.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
