From studying $\beta$-oxidation of free fatty acids, I've learned how to compute for the ATP equivalence of even-chain and odd-chain free fatty acids.
What really bothers me now is how to compute for the ATP equivalence of an unsaturated fatty acid. Since one of the major difference of the process is in unsaturated fatty acids, normal $\beta$-oxidation rounds will occur until the unsaturation is encountered. The cis-isomer will be converted to trans-isomer completely skipping the step where the fatty acyl-CoA molecule is oxidized to the trans-form with the release of FADH2.
Is the computation same and I just need to subtract a molecule of FADH2 per unsaturation (double bond)?
