User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is a phosphatidylcholine O-40:2 in which the alkyl and acyl groups at positions 1 and 2 are octadecyl and (13Z,16Z)-docosadienoyl respectively. It is a phosphatidylcholine O-40:2 and a 2-acyl-1-alkyl-sn-glycero-3-phosphocholine. It derives from a (13Z,16Z)-docosadienoic acid.
Assistant: This is a molecule that fits your description: CCCCC/C=C\C/C=C\CCCCCCCCCCCC(=O)O[C@H](COCCCCCCCCCCCCCCCCCC)COP(=O)([O-])OCC[N+](C)(C)C
