User: I want to come up with a molecule SMILES.
Assistant: This sounds very exciting. Should I consider any constraints for the creation?
User: Yes, please. The molecule can be described by:
The molecule is an N-acyl-15-methylhexadecasphing-4-enine-1-phosphocholine in which the acyl group has 20 carbons and 0 double bonds. It derives from a 15-methylhexadecasphing-4-enine.
Assistant: Got it, this SMILES fits your description: CCCCCCCCCCCCCCCCCCCC(=O)N[C@@H](COP(=O)([O-])OCC[N+](C)(C)C)[C@H](O)/C=C/CCCCCCCCCC(C)C
