Palmityl-3-one CoA

 

Step 4: Cleavage by CoA:

The final step is the cleavage of the acetyl CoA from the original fatty acid chain (16 carbons). At the same time, a new CoA molecule makes a new thioester bond to the # 3 or beta carbon carbonyl group. Notice that the final fatty acid molecule attached to the new CoA has two carbons less than when it started (14 carbons).
