This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Lipids, Subject name: Biochemistry
One of the following is obtained in the by beta oxidation of odd chain fatty acids: 
Select and explain. 
A. Acetyl-CoA + Acetyl-CoA, B. Acetyl-CoA + Propionyl-CoA, C. Propionyl CoA + Propionyl-CoA, D. Acetyl-CoA alone
B: Acetyl-CoA + Propionyl-CoA
Answer: B: Acetyl-CoA + Propionyl-CoA 
Explanation: Ans. B. Acetyl-CoA + Propionyl-CoA(Ref: Harper 31/e page 209)Oxidation of Odd Chain Fatty AcidTakes place in the mitochondria.Oxidation of a fatty acid with an odd number of carbon atoms yields acetyl-CoA and a molecule of propionyl-CoA.The propionyl residue from an odd-chain fatty acid is the only part of a fatty acid that is glucogenic
