A triglyceride contains three different fatty acids: 16:0 (palmitic, saturated), 18:1 cis (oleic, monounsaturated), and 22:6 (docosahexaenoic acid, polyunsaturated). Based on chain lengths and saturation, predict whether this triglyceride is more likely to be solid or liquid at room temperature and justify your answer.

• A. Solid at room temperature since the presence of any saturated fatty acid guarantees solidification by dominating intermolecular forces regardless of the number of double bonds in other chains.
• B. Liquid at room temperature, because the combined effect of one monounsaturated and one highly polyunsaturated chain prevents tight packing despite one saturated chain.
• C. Likely a crystalline solid unless the triglyceride is chemically modified, because triglycerides with long chains are always solids at room temperature.
• D. A brittle glassy polymer rather than a liquid or solid lipid, because the combination of various chain lengths always forms a cross-linked matrix at ambient conditions.

Answer: (B)
