Therefore, it is inferred that the number of acylcarnitines that may be formed with these fatty acids is very considerable. Similar to fatty acids, acylcarnitines are also differed by length of the acyl groups, often categorized as short, medium and long-chain acylcarnitines (simply marked as SCACs, MCACs and LCACs). Carnitine fundergoes reversible esterification of its 3-hydroxyl group producing acylcarnitine, which can enter the mitochondria with the assistance of specific translocases. Any deviation from the normal concentration in the blood circulation of an acylcarnitine, which is produced by reversible esterification of the 3-hydroxyl group of carnitine.
