Slightly different: L-carnitine is usually used to help with fat reduction; often used by body builders to help mobilize fat stores. Acetyl - l-carnitine is able to cross the blood-brain barrier, so is often used to help with mental clarity.

No difference: Both Amino Acid molecules are similar in action, & both are formed naturally in the body from carnitine, which is found in protein rich foods.
