Fatty acids containing 18 C atoms and a single double bond is____________?
Correct answer: C. Oleic Acid
- A. Saturated Fatty acid
- B. Unsaturated fatty acid
- C. Oleic Acid
- D. Plamitic acid
Explanation
Oleic acid is an 18-carbon fatty acid with one double bond, written as C18:1. Palmitic acid is the likely alternative because it is also a common long-chain fatty acid, but it is saturated and contains 16 carbon atoms, not 18.
