Now, remember that in the even chain fatty acid breakdown, we generate acetyl coenzyme A molecules only. And though the acetyl coenzyme A molecules are fed into the citric acid cycle to help generate, to help generate ATP molecules. But in the case of odd chain fatty acid breakdown, not only do we generate the acetyl coenzyme A, we also generate a proponel coenzyme A three carbon molecule. Now, what happens to this proponel coenzyme A? This will be the focus of this lecture. So basically, inside the matrix of the mitochondria, the proponel Co enzyme A molecule undergoes a three step process.
