Quizplus · Accepted Answer

The fatty acid given contains a branched chain structure, indicated by the presence of the ₃(CH₂)₉ segment. This suggests that the fatty acid is metabolized via the pathway of beta-oxidation with odd-carbon fatty acids, where the last step of each cycle results in the formation of propionyl-CoA. Therefore, after 30 minutes of oxidation, the label is most likely to be recovered in propionyl-CoA.
