Question: 158
8. Which fatty acid can be synthesized by humans?
- A. 12:00
- B. 16:00
- C. 16:01
- D. 18:03
Correct Answer: B
Explanation:
Humans can only synthesize one fatty acid, palmitic acid. Palmitic acid is fully saturated and therefore does not contain any double bonds. Palmitic acid has 16 carbons, and is synthesized from eight molecules of acetyl-CoA. In shorthand notation, palmitic acid is written as 16:0 (16 carbons, no double bonds).
