Fatty acid with even number of carbon atoms on oxidation produces:

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.
