User: I'm looking for the SMILES of a molecule that can be described by:
The molecule is a sphingomyelin 33:1 obtained by formal condensation of the carboxy group of hexadecanoic acid with the amino group of 15-methylhexadecasphingosine-1-phosphocholine. It is a metabolite of the nematode Caenorhabditis elegans. It has a role as a Caenorhabditis elegans metabolite. It derives from a 15-methylhexadecasphing-4-enine and a hexadecanoic acid.
Assistant: This is a molecule that fits this description: CCCCCCCCCCCCCCCC(=O)N[C@@H](COP(=O)([O-])OCC[N+](C)(C)C)[C@H](O)/C=C/CCCCCCCCCC(C)C
