Worked Solution & Example Answer:Which one of the following fatty acids is an omega-3 fatty acid? A - VCE - SSCE Chemistry - Question 8 - 2018 - Paper 1
Step 1
Which one of the following fatty acids is an omega-3 fatty acid?
Answer
To identify the omega-3 fatty acid among the options, we first recognize that omega-3 fatty acids are characterized by the presence of a double bond three carbons from the methyl end of the fatty acid chain.
Options Analysis:
- Arachidonic Acid - This is an omega-6 fatty acid, not omega-3.
- Palmitoleic Acid - This is a monounsaturated fatty acid and not classified as omega-3.
- Linolenic Acid - This is an essential omega-3 fatty acid, specifically alpha-linolenic acid (ALA).
- Linoleic Acid - This is an omega-6 fatty acid, not omega-3.
Thus, the correct answer is C. linolenic, as it is the only option that qualifies as an omega-3 fatty acid.
