[{'content': 'b-Oxidation of odd-carbon fatty acid chain produces: \nSelect and explain. \nA. Succinyl CoA, B. Propionyl CoA, C. Acetyl CoA, D. Malonyl CoA', 'role': 'user'}, {'content': 'Answer: B \nExplanation: Ans. B. Propionyl CoAb-Oxidation is the oxidation of carbon which is adjacent to a-carbon atom. It takes place in the mitochondria. b-Oxidation is accomplished by repetitive 4 steps to finally get Acetyl CoA (from even chain fatty acids) and propionyl CoA (from odd chain fatty acids). The four main steps are dehydrogenation, hydration, oxidation and thiolytic cleavage.', 'role': 'assistant'}]
