This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Beta oxidation of fatty acids, Subject name: Biochemistry
Major end product of beta oxidation of odd chain fatty acids: 
Select and explain. 
A. Propionyl CoA, B. Succinyl CoA, C. Acetyl CoA, D. Malonyl CoA
C: Acetyl CoA
Answer: C: Acetyl CoA 
Explanation: Odd chain fatty acid on beta-oxidation Give many Acetyl CoA (released at every step) and only 1 Propionyl CoA. In 17 C fatty acid ( odd chain ) , when it's broken down , 7 molecules of acetyl CoA ( 14 C)and 1 molecule of propionyl CoA (3C) are obtained So, major end product is Acetyl CoA whereas Propionyl CoA is a minor end product.
