Carnitine palmitoyltransferase (CPT I and CPT II) are involved in the transport of long-chain fatty acids into the mitochondria where they are oxidized. Fatty acids form a conjugate with CoA before being oxidized in the mitochondria. However, the CoA-long-chain fatty acid conjugates can not diffuse into the mitochondria. CPT I is a membrane protein which substitutes the CoA in the long-chain fatty acids by carnitine. After entering the mitochondria, CPT II exchanges the carnitine by CoA, enabling the oxidation of the long-chain fatty acids. CPT I is important in fatty acid disorders like diabetes.
