The Uses of D(+)-Carnitine
Essential cofactor of fatty acid metabolism; required for the transport of fatty acids through the inner mitochondrial membrane. Synthetized primarily in the liver and kidney; highest concentrations found in heart and skeletal muscle. Dietary sources include red meat, dairy products, beans, avocado.
Definition
ChEBI: The (S)-enantiomer of carnitine.
Purification Methods
The S(L) isomer is levocarnitine, Vitamin B7. The R or S isomers crystallise from EtOH/Me2CO (hygroscopic). The R or S hydrochlorides crystallise from hot EtOH or EtOH/Et2O and have m 142o(dec). The RS-isomer crystallises from hot EtOH (hygroscopic). The RS hydrochloride crystallises in needles from hot EtOH and has m 196o(dec).
