Carnitine is an important factor for the transport of long-chain fatty acids bound to carnitine (carnitine acyltransferase) into the mitochondrial matrix for subsequent β-oxidation. There are two enantiomers: D- and L-carnitine. Only the L-isomer is physiologically active.

Abbreviation: Car

Application in HRR

Car: Carnitine (L-Carnitine inner salt; C7H15NO3), Sigma-Aldrich: C0158, store at RT, CAS: 541-15-1, M = 161.2 g·mol-1

Preparation of 250 mM stock solution (dissolved in H2O)
  1. Weigh 100 mg of Carnitine.
  2. Add 2.48 mL H2O.
  3. Divide into 100 µL portions.
  4. Store frozen at -20°C.
