[{'content': 'Fatty acid with even number of carbon atoms on oxidation produces: \nSelect and explain. \nA. Acetyl CoA, B. Succinyl CoA, C. Propionyl CoA, D. All of the above', 'role': 'user'}, {'content': 'Answer: A \nExplanation: Fatty acids with an odd number of carbon atoms are oxidized by the pathway of b-oxidation, producing acetyl-CoA, until a three-carbon (propionyl-CoA) residue remains. This compound is conveed to succinyl-CoA, a constituent of the citric acid cycle. Hence, the propionyl residue from an odd-chain fatty acid is the only pa of a fatty acid that is glucogenic Ref: Harper 28th edition, chapter 22.', 'role': 'assistant'}]
