Background
Palmitoyl-L-carnitine-d3 is intended for use as an internal standard for the quantification of palmitoyl-L-carnitine by GC- or LC-MS. Palmitoyl-L-carnitine is a naturally occurring long-chain acylcarnitine and the L-enantiomer of palmitoyl-DL-carnitine .1 In cells, palmitoyl-L-carnitine is transported into mitochondria via carnitine palmitoyl transferase II to deliver palmitate for fatty acid oxidation and energy production.2 It also inhibits lecithin:cholesterol acyltransferase activity in rat, but not human, plasma when used at a concentration of 500 µM.3 In vivo, palmitoyl-L-carnitine increases intestinal absorption of the antibiotic cefoxitin in rat intestine.4
