Question

Example of a 4 point question: Question: You have two fats, one is from an animal and one is from a plant. Knowing that saturated fat is used for energy and hormone production; would you expect animal or plant fat to be liquid at room temperature? Be sure to discuss melting point in your answer. Answer: Because the function of saturated fat hints that it is more common in animals rather than plants, we can come to the conclusion that plant fat is more likely to be liquid at room temperature because it is more likely tobe an unsaturated fat. The greater number of unsaturated bonds, the lower the melting point.
