[{"from": "human", "value": "Create a molecule with the structure as the one described. The molecule is an L-alpha-amino acid zwitterion formed from ovothiol A by transfer of a proton from the carboxy to the amino group; major species at pH 7.3. It is functionally related to a L-histidine zwitterion. It is a tautomer of an ovothiol A."}, {"from": "gpt", "value": "[C][N][C][=N][C][=Branch1][=C][=C][Ring1][Branch1][C][C@@H1][Branch1][=Branch1][C][=Branch1][C][=O][O-1][NH3+1][S]"}]
