is acetyl CoA a hormone
Another regulation of Acetyl-CoA carboxylase is by hormones. Glucagon, epinephrine, and norepinephrine trigger a cAMP dependent phosphorylation (remember the cascade system) of the enzyme that shifts the equilibrium towards monomer formation.Insulin, conversely, stimulates desphosphorylation, favoring polymerization.ransport of Mitochondrial Acetyl-CoA into the Cytosol. Acetyl-CoA is produced in two ways in the mitochondria 1  -. by Beta-oxidation of fatty acids, and. 2  by combined action of pyruvate dehydrogenase (to decarboxylate pyruvate, producing acetate) and dihydrolipoyl transacetylase (to add the CoA to the acetate).
