Beta oxidation of myristoyl-CoA to lauroyl-CoA

The second pass through the beta-oxidation spiral starts with the saturated fatty acid myristoyl-CoA (from the first swing through the beta oxidation spiral) and produces lauroyl-CoA. Four enzymatic steps are required starting with LCAD CoA dehydrogenase (Long Chain) activity, followed by three enzymatic steps, enoyl-CoA hydratase, 3-hydroxyacyl-CoA dehydrogenase, and ketoacyl-CoA thiolase activities, all present in the mitochondrial membrane associated trifunctional protein.
