User: I want to create a SMILES.
Assistant: This sounds very interesting. Should it be a special one?
User: Yes, the molecule can be described as:
The molecule is dizwitterionic form of homocystine arising from transfer of two protons from the carboxy to the amino groups; major species at pH 7.3. It has a role as a human metabolite. It is a tautomer of a homocystine.
Assistant: Ok, this SMILES fits this description: [NH3+]C(CCSSCCC([NH3+])C(=O)[O-])C(=O)[O-]
