So cyclic Amp binds onto the regulatory units of the PKA. That causes the dissociation of the catalytic units from the PKA, and that activates the PKA. And once the PKA is actually activated, protein kinase A goes on to phosphorylate and activate two important types of enzymes involved in the breakdown and the mobilization of triglyceride. So what are these important enzymes? Well, one of them is known as parolipin A, and the other set of enzymes are known as hormone sensitive lipases. So these two enzymes work together to basically help break down these triglycerides into fatty acids and glycerol molecules.
