Carnitine shuttle system

In the second reaction, acyl-CoA is transiently attached to the hydroxyl group of carnitine to form fatty acylcarnitine. This transesterification is catalyzed by an enzyme found in the outer membrane of the mitochondria known as carnitine acyltransferase 1 (also called carnitine palmitoyltransferase 1, CPT1).
