Polysaccharides are:
Correct answer: B. Sparingly soluble in hot water
- A. Insoluble in hot water
- B. Sparingly soluble in hot water
- C. Sparingly soluble in cold water
- D. Highly soluble in hot water
Explanation
Polysaccharides, composed of long chains of monosaccharide units, exhibit limited solubility in hot water due to their complex molecular structure. While monosaccharides and disaccharides dissolve more readily, polysaccharides only dissolve to a limited extent in hot water, making Option B correct. Options A and D incorrectly suggest they are either insoluble or highly soluble in hot water. Option C is incorrect because polysaccharides have even lower solubility in cold water.

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.
