Task: Please create a text description for a molecule based on its representation.
SMILES: [NH3+][C@@H](Cc1[nH]cnc1S(=O)C[C@H]([NH3+])C(=O)[O-])C(=O)[O-]
Constraint: Answer the question with complete sentences.
Result: The molecule is an L-alpha-amino acid zwitterion formed from S-(5-histidyl)cysteine sulfoxide by transfer of protons from the two carboxy to the two amino grousp; major species at pH 7.3. It derives from a L-histidine zwitterion and a L-cysteine zwitterion. It is a tautomer of a S-(5-histidyl)cysteine sulfoxide.
