User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is a phosphatidylcholine 24:0 in which the acyl groups specified at positions 1 and 2 are undecanoyl and tridecanoyl respectively. It derives from an undecanoic acid and a tridecanoic acid.
Assistant: This is a molecule that fits this description: CCCCCCCCCCCCC(=O)O[C@H](COC(=O)CCCCCCCCCC)COP(=O)([O-])OCC[N+](C)(C)C
