Task: Please create a description for a molecule based on its representation.
Molecule SMILES: [NH3+][C@@H](CCSC[C@H]1OC(O)[C@H](O)[C@@H]1O)C(=O)[O-]
Constraint: Answer the question with complete sentences.
Result: The molecule is zwitterionic form of S-(5-deoxy-D-ribos-5-yl)-L-homocysteine arising from transfer of a proton from the carboxy to the amino group; major species at pH 7.3. It is a tautomer of a S-(5-deoxy-D-ribos-5-yl)-L-homocysteine.
