User: I want to create a SMILES.
Assistant: This sounds very exciting. Should I consider any specific points for the generation?
User: Yes, please. The molecule can be described as:
The molecule is dizwitterionic form of L-cystathionine arising from transfer of two protons from the carboxy to the amino groups; major species at pH 7.3. It is a tautomer of a L-cystathionine.
Assistant: Got it, this SMILES fits this description: [NH3+][C@@H](CCSC[C@H]([NH3+])C(=O)[O-])C(=O)[O-]
