Question

g Consider the fatty acid. A carboxylate salt is attached to a 19 carbon chain, where double bonds are present between carbons 5 and 6, between carbons 8 and 9, between carbons 11 and 12, and between 14 and 15. The carboxylate carbon is carbon 1. All double bonds are cis. Which of the designations are accurate for the fatty acid? ) ω-3 fatty acid ω‑6 fatty acid ) 4,7,10,13-nonadecatetraenoic acid

Answer 1

The fatty acid described is a ω‑6 fatty acid. As you can see in the picture, the last carbon opposite to carboxyl is the carbon number one. Then, start to count until the first double bounded carbon in this case carbon 6, giving the designation of this fatty acid as ω‑6 fatty acid.
