Palmitoylcarnitine is an ester derivative of carnitine (long-chain acylcarnitine) involved in the metabolism of fatty acids. Within the cell, palmitoylcarnitine is transported into the mitochondria to deliver palmitate for fatty acid oxidation and energy production.

Abbreviation: Pal

Carnitine palmitoyltransferase I (CPT1) also known as carnitine acyltransferase I or CAT1 is a mitochondrial enzyme. CPT1 is associated with the outer mitochondrial membrane and mediates the transport of long-chain fatty acids across the membrane by binding them to carnitine.

Application in HRR

Pal: Palmitoylcarnitine (Palmitoyl-DL-carnitine-HCl; C23H46NO4 · Cl), Sigma-Aldrich: P4509, store at -20 °C, CAS: 6865-14-1, M = 436.07 g·mol-1

Preparation of 10 mM stock solution (dissolved in H2O):
  1. Weigh 8.72 mg of palmitoylcarnitine.
  2. Dissolve in 2 mL H2O.
  3. Divide into 0.2 mL portions.
  4. Store frozen at -20 °C.
