Notes: Palmitoyl-L-carnitine-d3 is intended for use as an internal standard for the quantification of palmitoyl-L-carnitine (Item No. 26553) by GC- or LC-MS. Palmitoyl-L-carnitine is a naturally occurring long-chain acylcarnitine and the L-enantiomer of palmitoyl-DL-carnitine (Item No. 11095).{20215} In cells, palmitoyl-L-carnitine is transported into mitochondria via carnitine palmitoyl transferase II to deliver palmitate for fatty acid oxidation and energy production.{20218} It also inhibits lecithin:cholesterol acyltransferase activity in rat, but not human, plasma when used at a concentration of 500 µM.{42574} In vivo, palmitoyl-L-carnitine increases intestinal absorption of the antibiotic cefoxitin (Item No. 15990) in rat intestine.{46086}
