User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a 2-acyl-1-alkyl-sn-glycero-3-phosphocholine in which the alkyl and the acyl groups at positions 1 and 2 are hexadecyl and butanoyl respectively. It is a 2-acyl-1-alkyl-sn-glycero-3-phosphocholine and a butyrate ester.
Assistant: This is a molecule that fits your description: CCCCCCCCCCCCCCCCOC[C@H](COP(=O)([O-])OCC[N+](C)(C)C)OC(=O)CCC
