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. amount abnormal blood
