User: I want to come up with a SMILES.
Assistant: This sounds very interesting. Should it be a special one?
User: Yes, the molecule can be described by:
The molecule is a cysteine zwitterion derived from D-cysteine by transfer of a proton from each of the carboxy groups to the amino groups. It is an enantiomer of a L-cystine zwitterion. It is a tautomer of a D-cystine.
Assistant: Ok, this SMILES fits your description: [NH3+][C@H](CSSC[C@@H]([NH3+])C(=O)[O-])C(=O)[O-]
