[{"from": "human", "value": "Based on the given information, design a molecule that meets the desired specifications. The molecule is a peptide zwitterion that is the dizwitterionic form of neurotensin (1-8) having both carboxy groups deprotonated and the side-chains of L-lysyl and L-arginine protonated. It is the major species at pH 7.3. It is a tautomer of a neurotensin (1-8)."}, {"from": "gpt", "value": "[C][C][Branch1][C][C][C][C@@H1][Branch2][#Branch1][S][C][=Branch1][C][=O][N][C@@H1][Branch1][=N][C][C][=C][C][=C][Branch1][Branch1][C][=C][Ring1][=Branch1][O][C][=Branch1][C][=O][N][C@@H1][Branch1][Branch2][C][C][C][=Branch1][C][=O][O-1][C][=Branch1][C][=O][N][C@@H1][Branch1][#Branch1][C][C][=Branch1][C][=O][N][C][=Branch1][C][=O][N][C@@H1][Branch1][=Branch1][C][C][C][C][NH3+1][C][=Branch1][C][=O][N][C][C][C][C@H1][Ring1][Branch1][C][=Branch1][C][=O][N][C@@H1][Branch1][#Branch2][C][C][C][NH1+1][=C][Branch1][C][N][N][C][=Branch1][C][=O][O-1][N][C][=Branch1][C][=O][C@@H1][C][C][C][=Branch1][C][=O][N][Ring1][=Branch1]"}]
