User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a 1,2-dialkyl-sn-glycero-3-phosphocholine in which the 1- and 2- alkyl groups are specified as [3]-ladderanehexanyl and [3]-ladderaneoctanyl respectively. It has a role as a human xenobiotic metabolite.
Assistant: This is a molecule that fits this description: C[N+](C)(C)CCOP(=O)([O-])OC[C@@H](COCCCCCCC1CCC2C(C1)C1C3CCC3C21)OCCCCCCCCC1CCC2C(C1)C1C3CCC3C21
