User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is an N-acylphytosphingosine-1-phosphoethanolamine zwitterion in which the N-acyl group is specified as hexadecanoyl. It derives from a N-hexadecanoylphytosphingosine. It is a tautomer of a N-hexadecanoylphytosphingosine-1-phosphoethanolamine.
Assistant: This is a molecule that fits this description: CCCCCCCCCCCCCCCC(=O)N[C@@H](COP(=O)([O-])OCC[NH3+])[C@H](O)[C@H](O)CCCCCCCCCCCCCC
