So two of those carbon atoms basically came from these this acetyl coenzyme A molecule and the other two came from this acetyl coenzyme A molecule. Now, what happens next? Because ultimately we said that fatty acid synthase can generate a 16 carbon fatty acid molecule. So what happens next is is this cycle basically takes place six more times. And when it takes place six more times, it generates a 16 carbon palmitate a 16 carbon palmitate fatty acid molecule. So quickly, let's talk about how that actually takes place.
