A distinguishing characteristic of lipids compared to other major biological molecules is their

A. High solubility in water and low solubility in non-polar solvents
B. High solubility in non-polar solvents and low solubility in water
✓
C. Monomeric composition of nucleotides
D. Rapid turnover rate as a primary energy source

📝 Explanation

Lipids are defined by their hydrophobic nature, being soluble in non-polar organic solvents (like ether, chloroform) but insoluble in water. This contrasts with carbohydrates and proteins which are generally hydrophilic.
