Which of the following statements are true? a. triacylglycerols (triglycerides) always contain three identical fatty acids. b. unsaturated fats are more likely than saturated fats to be liquid at room temperature. c. triacylglycerols (triglycerides) are composed of fatty acid residues and glycerold. saturated fats have lower melting points than do unsaturated fats. e. fats that contain more unsaturated fatty acid residues than saturated fatty acid residues are more likely to be liquid at room temperature.

B, C, E.

Explanation:

Unsaturated fats are more likely than saturated fats to be liquid at room temperature. (because saturated fats are solid at room temperature and unsaturated fats are liquid at room temperature).

Triacylglycerols (triglycerides) are composed of fatty acid residues and glycerol. (because by the reaction between glycerol and 3 long chain fatty acid triglycerides formation occurs and form 3 ester linkages).

Fats that contain more unsaturated fatty acid residues than saturated fatty acid residues are more likely to be liquid at room temperature. (because saturated fats are solid at room temperature and unsaturated fats are liquid at room temperature).
