Which structural feature accurately describes a triglyceride molecule?

• A. A carbohydrate backbone with three mono-unsaturated side chains that always confer liquid state at room temperature regardless of chain length.
• B. A glycerol backbone esterified to three fatty acids, where chain length and saturation of those fatty acids influence physical properties like melting point.
• C. A three‑ringed sterol core attached to three phosphate groups that determine the molecule's amphipathic character and membrane roles.
• D. Two glycerol molecules linked head-to-head with a single very long polyunsaturated fatty acid bridging them to make an amphiphilic bilayer-forming lipid.

Answer: (B)
