#### Multiple-Choice Questions
**17. A polyunsaturated fatty acid contains multiple:**
- a. ketones.
- b. carboxylic acids.
- c. carbon-carbon double bonds.
- d. alcohols.
- e. Any of the above.
**18. Which of the following choices correctly numbers linolenic acid (shown below) using the delta system?**
![Diagram of Linolenic Acid](#)
- a. Δ9,12,15
- b. Δ9
- c. Δ3,6,9
- d. Δ3,5,9
- e. Δ9,12
**19. Which of the fatty acids shown below are saturated?**
- Structure diagrams for the following:
- **Stearic Acid**
- **Linolenic Acid**
- **Arachidonic Acid**
**Descriptions of Structures:**
1. **Stearic Acid:**
- A long-chain saturated fatty acid with no double bonds, linear in structure.
2. **Linolenic Acid:**
- A polyunsaturated fatty acid with three double bonds, causing bends in its structure.
3. **Arachidonic Acid:**
- A polyunsaturated fatty acid, containing multiple double bonds, showing a more complex structure.
**Conceptual Explanation:**
- **Saturated fatty acids** have no carbon-carbon double bonds, resulting in straight chains that pack closely together. This characteristic gives them a solid form at room temperature.
- **Polyunsaturated fatty acids**, like linolenic acid, have multiple double bonds, introducing kinks that prevent close packing and result in a liquid form at room temperature.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc0da3887-c4ea-4b9e-9efc-f9c8b5a90f3a%2F62516cdd-c47d-470d-affb-deb08edbf35a%2Fa6ywz2_processed.jpeg&w=3840&q=75)
