The table shows some differences between glucose and a triglyceride. Which difference explains the fact that glucose is soluble in water, while the triglyceride is insoluble in water?
Correct answer: A. Option A
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
The correct answer is Option A. Glucose is soluble in water because it contains many polar hydroxyl (-OH) groups that can form hydrogen bonds with water molecules, facilitating its dissolution. This is a characteristic of polar molecules, making them hydrophilic. On the other hand, triglycerides are composed of long non-polar hydrocarbon chains, which repel water, making them insoluble (hydrophobic). Although options B, C, and D mention other molecular properties, they do not directly explain the difference in solubility between glucose and triglycerides.

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.
