User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a sphingomyelin d18:1 in which the ceramide N-acyl group is specified as (11Z)-icosenoyl. It has a role as a mouse metabolite. It is a sphingomyelin d18:1 and a sphingomyelin 38:2. It derives from an (11Z)-icos-11-enoic acid.
Assistant: This is a molecule that fits your description: CCCCCCCC/C=C\CCCCCCCCCC(=O)N[C@@H](COP(=O)([O-])OCC[N+](C)(C)C)[C@H](O)/C=C/CCCCCCCCCCCCC
