substance L-carnitine. It is reported to be useful in the treatment of cognition disorders in the elderly, perhaps due to its weak cholinergic properties.

O-Acetyl-L-carnitine hydrochloride is used as a cholinergic agonist that stimulates neuronal response to serotonin and acetylcholine. Acetylcarnitine has antinociceptive activity that may be mediated by enhanced activity of muscarinic cholinergic receptors or mGlu2 glutamate receptors.

Acetyl-L-carnitine (ALC/ALCAR), a quasi-vitamin is a metabolite of carnitine, present in mammalian plasma and tissues. It is the acetylated form of L-carnitine (LC). ALCAR is used as a dietary supplement. It is present at high level in the hypothalamus.
Purification Methods
Recrystallise the chloride from isopropanol. Dry it over P2O5 under high vacuum. The S-betaine crystallises from EtOH/Et2O with m 145o(dec) and is hygroscopic; it has [] D -19.5o (c 6, H2O).
