Task: Please create a description for a molecule.
SMILES: [NH3+][C@@H](CCSC[C@H]([NH3+])C(=O)[O-])C(=O)[O-]
Constraint: Answer the question with full sentences.
Result: 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.
