User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a sphingomyelin 34:1 obtained by formal condensation of the carboxy group of octadecanoic acid with the amino group of hexadecasphingosine-1-phosphocholine. It has a role as a Papio hamadryas metabolite. It derives from a hexadecasphing-4-enine and an octadecanoic acid.
Assistant: This is a molecule that fits your description: CCCCCCCCCCC/C=C/[C@@H](O)[C@H](COP(=O)([O-])OCC[N+](C)(C)C)NC(=O)CCCCCCCCCCCCCCCCC
