User: I'm looking for the SMILES of a molecule that can be described by:
The molecule is a phosphatidylcholine 42:1 in which the acyl groups specified at positions 1 and 2 are octadecanoyl and (15Z)-tetracosenoyl respectively. It derives from an octadecanoic acid and a (15Z)-tetracosenoic acid.
Assistant: This is a molecule that fits this description: CCCCCCCC/C=C\CCCCCCCCCCCCCC(=O)O[C@H](COC(=O)CCCCCCCCCCCCCCCCC)COP(=O)([O-])OCC[N+](C)(C)C
