Question: 70
10. Which of the following statements about saturation is FALSE?
- A. It can describe the number of double or triple bonds in a fatty acid tail.
- B. It determines at least one of the properties of membranes.
- C. More saturated fatty acids make for a more fluid solution.
- D. Fully saturated fatty acids have only single bonds.
Correct Answer: C
Explanation:
More saturated fatty acids make for a less fluid solution. This is because they can pack more tightly and form more noncovalent bonds, resulting in more energy being needed to disrupt the overall structure.
