Acyl-CoA can pass through porins in the outer membrane, but it needs the assistance of carnitine in order to move through the inner membrane.

Note: Acyl-CoA is different than Acetyl-CoA, as Acyl-CoA is a classifiable molecule, since it has a generic R- group while acetyl-CoA is an identifiable molecule.

Another Note: CoA is short for Coenzyme A. It consists of a ß-mercapto-ethylamine group, attached to a pantothenic group, attached to a 3',5' - Adenine DiPhosphate, in that order. The ß-mercapto-ethylamine group is connected to the Acetyl unit, by an acetyl thioester bond.
Structure of coenzyme A: 1: 3′-phosphoadenosine. 2: diphosphate, organophosphate anhydride. 3: pantoic acid. 4: β-alanine. 5: cysteamine.
