EPA and DHA acylcarnitines are less cardiotoxic than are saturated and monounsaturated long-chain acylcarnitines.

ABSTRACT: Elevated levels of fatty acid-derived long-chain acylcarnitines are detrimental to cardiac health, primarily because of their adverse effects on mitochondrial function and key metabolic pathways in the heart. While trans-fatty acids are considered harmful and omega-3 polyunsaturated fatty acids (PUFAs) are considered beneficial, the specific properties of acylcarnitines derived from these types of fatty acids are not characterized. This study aimed to compare the effects of saturated palmitoylcarnitine (PC), monounsaturated cis-oleoylcarnitine (cis-OC), trans-elaidoylcarnitine (trans-EC), and polyunsaturated eicosapentaenoylcarnitine (EPAC) and docosahexaenoylcarnitine (DHAC) on heart function, cardiac cell viability, mitochondrial functionality, and insulin signaling pathways.
