User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is zwitterionic form of psychosine sulfate arising from transfer of a proton from the sulfo to the amino group; major species at pH 7.3. It is a tautomer of a psychosine sulfate.
Assistant: This is a molecule that fits this description: CCCCCCCCCCCCC/C=C/[C@@H](O)[C@@H]([NH3+])CO[C@@H]1O[C@H](COS(=O)(=O)[O-])[C@H](O)[C@H](O)[C@H]1O
