Contains FAD as prosthetic group. One of several enzymes that catalyse the first step in fatty acids beta-oxidation. The enzyme from pig liver can accept substrates with acyl chain lengths of 6 to at least 16 carbon atoms. The highest activity was found with C12, and the rates with C8 and C16 were 80 and 70%, respectively . The enzyme from rat can accept substrates with C8-C22. It is most active with C14 and C16, and has no activity with C4, C6 or C24 . cf. EC 188.8.131.52, short-chain acyl-CoA dehydrogenase, EC 184.108.40.206, medium-chain acyl-CoA dehydrogenase, and EC 220.127.116.11, very-long-chain acyl-CoA dehydrogenase.

Purification and characterization of short-chain, medium-chain, and long-chain acyl-CoA dehydrogenases from rat liver mitochondria. Isolation of the holo- and apoenzymes and conversion of the apoenzyme to the holoenzyme.
