User: Can you create the SMILES of a molecule based in this description:
The molecule is an optically active form of O-butanoylcarnitine having L-configuration. It has a role as a metabolite. It is an O-butanoylcarnitine and a saturated fatty acyl-L-carnitine.
Assistant: Sure, here you go: CCCC(=O)O[C@H](CC(=O)[O-])C[N+](C)(C)C
User: Can you {#give me|create|generate!} the {SMILES__description} of a molecule based in this description:
