Carnitine O-palmitoyltransferase
Carnitine O-palmitoyltransferase (also called carnitine palmitoyltransferase) is a mitochondrial transferase enzyme (EC 2.3.1.21) involved in the metabolism of palmitoylcarnitine into palmitoyl-CoA. A related transferase is carnitine acyltransferase.

Human forms
There are four different forms of CPT in humans:
- CPT1A – associated with Carnitine palmitoyltransferase I deficiency
- CPT1B
- CPT1C
- CPT2 – associated with carnitine palmitoyltransferase II deficiency
