User: I'm looking for the SMILES of a molecule that can be described by:
The molecule is a phosphatidylcholine 38:0 in which the acyl groups at positions 1 and 2 are specified as eicosanoyl and octadecanoyl respectively. It derives from an icosanoic acid and an octadecanoic acid.
Assistant: This is a molecule that fits this description: CCCCCCCCCCCCCCCCCCCC(=O)OC[C@H](COP(=O)([O-])OCC[N+](C)(C)C)OC(=O)CCCCCCCCCCCCCCCCC
