Fatty acid with even number of carbon atoms on oxidation produces:: (A) Acetyl CoA, (B) Succinyl CoA, (C) Propionyl CoA, (D) All of the above
Answer is A. Fatty acids with an odd number of carbon atoms are oxidized by the pathway of b-oxidation, producing acetyl-CoA, until a three-carbon (propionyl-CoA) residue remains. This compound is conveed to succinyl-CoA, a constituent of the citric acid cycle. Hence, the propionyl residue from an odd-chain fatty acid is the only pa of a fatty acid that is glucogenic Ref: Harper 28th edition, chapter 22.
