Acetyl-L-Carnitine

Acetyl-L-carnitine is similar in form to the amino acid L-carnitine and also has some similar functions, such as being involved in the metabolism of food into energy. The acetyl group that is part of acetyl-L-carnitine contributes to the production of the neurotransmitter acetylcholine, which is required for mental function.
