[{'content': 'Oxidation of a fatty acid with an odd number of carbon atoms yields: \nSelect and explain. \nA. Acetyl-CoA plus a molecule of Propionyl-CoA, B. Two molecules of Acetyl CoA, C. Two molecules of Propionyl CoA, D. Acetyl CoA only', 'role': 'user'}, {'content': 'Answer: A \nExplanation: Fatty acids with an odd number of carbon atoms are oxidized by\xa0 the\xa0 pathway\xa0 of\xa0 β xidation\xa0 described\xa0 above\xa0 producing acetyl\xa0 CoA\xa0 until\xa0 a\xa0 three-carbon\xa0 (propionyl-CoA)\xa0 residue remains. This compound is converted to succinyl-CoA, a constituent of the citric acid cycle. Hence, the propionyl residue from an odd-chain fatty acid is the only part of a fatty acid that is glucogenic.\nHARPERS ILLUSTRATED BIOCHEMISTRY30th ed, Page No:225', 'role': 'assistant'}]
