Odd-chain fatty acid oxidation
β-Oxidation of a fatty acid with an odd number of carbons differs from even-chain oxidation because its final cycle produces:
Answer B: explanation for every choice
A
Two acetyl-CoA from the final cycle is the even-chain result.
B
Correct. The three-carbon propionyl-CoA is converted to succinyl-CoA, which can enter the citric acid cycle and support gluconeogenesis.
C
Malonyl-CoA is an intermediate of fatty acid synthesis.
D
β-Oxidation doesn't produce glucose directly.
TakeawayOdd-chain fatty acids → propionyl-CoA → succinyl-CoA, a small glucogenic contribution.
