Which of the statements are true? Triacylglycerols (triglycerides) contain ester bonds. Triacylglycerols (triglycerides) are carboxylic acids. Fats that contain more unsaturated fatty acid residues than saturated fatty acid residues are more likely to be liquid at room temperature. Unsaturated fats have higher melting points than saturated fats. Saturated fats are more likely than unsaturated fats to be solid at room temperature.

Which of the statements are true?
Triacylglycerols (triglycerides) contain ester bonds.
Triacylglycerols (triglycerides) are carboxylic acids.
Fats that contain more unsaturated fatty acid residues than saturated fatty acid residues are more likely to be liquid at room temperature.
Unsaturated fats have higher melting points than saturated fats.
Saturated fats are more likely than unsaturated fats to be solid at room temperature.

Answer

• Triacylglycerols (triglycerides) contain ester bonds.
  Fats that contain more unsaturated fatty acid residues than saturated fatty acid residues are more likely to be liquid at room temperature.
  Saturated fats are more likely than unsaturated fats to be solid at room temperature.
  Explanation:
  Triacylglycerols have their glycerol molecule attached to fatty acids through an ester linkage.The kinks of unsaturated fat molecules keep them liquid at room temperature. Unsaturated fatty acids have lower melting point than saturated fatty acids of the same length, that’s why, most saturated fats are solid at room temperature while unsaturated fats of the same length are more likely to be liquid at room temperature.
