SCI260 – Introduction to BiochemistryLesson 61. Describe (in words) the overall structure of a lipid bilayer.2. What are the properties (i.e., characteristics) of the lipid bilayer of a cell thatmake it impermeable to ions and most molecules?3. Describe the role of cholesterol in maintaining the fluidity of the lipid bilayer of acell?4. The triglycerides in animals tend to be solids (i.e., fats) at room temperaturewhereas the triglycerides in plants tend to be liquids (i.e., oils) at roomtemperature. Based on this fact, what can you conclude about the characteristicsof the fatty acids in animal triglycerides compared to the fatty acids in planttriglycerides?5. Peanut oil contains a high percentage of monounsaturated triglycerides whereasvegetable oil contains a higher percentage of polyunsaturated triacylglycerols. Abottle of peanut oil and a bottle of vegetable oil are stored in a pantry with anoutside wall. During a cold spell, the peanut oil freezes, but the vegetable oilremains liquid. Explain why.6. How many molecules of ATP are generated when stearic acid (i.e., stearate), an18-carbon saturated fatty acid, is completely oxidized via the beta-oxidationpathway in the mitochondria?a) 112b) 129c) 146d) 1637. Which of the following fatty acids below are essential for humans? *Select one ormore.a) Oleic acidb) Linoleic acidc) Linolenic acidd) Palmitoleic acide) Eicosapentaenoic acid (EPA)8. Refer to Question 7, look up the structures of each fatty acid that is essential andexplain why they are essential for humans?9. Are trans fatty acids saturated or unsaturated?10. Provide four (4) examples of foods that contain trans fatty acids.You may use your textbook and/or the internet to assist you. You will earn 10 points forcorrectly answering each question (maximum points earned = 100 points).
