These are properties of lipids:
Correct answer: D. All of these
- A. Insoluble in water and soluble in fat solvent.
- B. High energy content
- C. Structural component of cell membrane
- D. All of these
Explanation
Fats are insoluble in water because water is polar and fats are non polar, hence making them fat soluble only. It is present in cells in the membrane, and due to its insolubility in water helps play the structural role. Fats also provide a decent amount of energy in cells.

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.
