[{'content': 'In a well fed state, acetyl CoA obtained from diet is least used in the synthesis of \nSelect and explain. \nA. Palmity CoA, B. Citrate, C. Acetoacetate, D. Oxalosuccinate', 'role': 'user'}, {'content': 'Answer: C \nExplanation: Ketone bodies (acetoacetate) synthesis is decreased in fed state, so acetyl-CoA is not used for synthesis of ketone bodies in fed state.\n\nAbout other options\n\nFatty acid (palimitoyl CoA) synthesis is increased in fed state. Fatty acids are synthesized from acetyl-CoA.\nIn fed state acetyl-CoA is oxidized via TCA cycle. Acetyl-CoA condenses with oxaloacetate to form citrate.\nOxalosuccinate is an intermediate of TCA cycle.', 'role': 'assistant'}]
