Is Arachidonic acid considered an Omega 3 or Omega 6 fatty acid?

• A. Omega 3
• B. Omega 6
• C. Both
• D. Neither

Answer: (B)

Arachidonic acid is classified as an Omega 6 fatty acid because of its chemical structure and the position of the first double bond in relation to the methyl end of the fatty acid chain. In Omega 6 fatty acids, the first double bond occurs at the sixth carbon atom from the methyl end of the fatty acid. Arachidonic acid consists of a 20-carbon chain with four double bonds, and its first double bond is precisely located at the sixth carbon, confirming its identification as an Omega 6 fatty acid. In contrast, Omega 3 fatty acids have their first double bond located at the third carbon from the methyl end. This distinction in the location of the first double bond differentiates Omega 3 from Omega 6 fatty acids. Therefore, classifying arachidonic acid as Omega 6 is correct, as this classification is based strictly on the structural characteristics of the fatty acid itself.
