[{"from": "human", "value": "Synthesize a molecule that matches the given characteristics. The molecule is poly-L-lysine (n > 40) in which 50-70% of the epsilon-amino groups are substituted with benzylpenicilloyl groups. It is used as a skin-testing reagent to detect immunoglobulin E antibodies in people with a history of penicillin allergy. It has a role as a diagnostic agent. It is a thiazolidinemonocarboxylic acid, a random copolymer, an amino acid amide and a polypeptide. It is functionally related to a benzylpenicillin."}, {"from": "gpt", "value": "[C][C][Branch2][Branch1][Branch1][C@@H1][Branch2][Ring2][N][N][C@H1][Branch1][Ring2][S][Ring1][Branch1][C][Branch2][Ring1][Ring1][C][=Branch1][C][=O][N][C][C][C][C][C@H1][Branch1][=Branch1][C][=Branch1][C][=O][O][N][N][C][=Branch1][C][=O][C][C][=C][C][=C][C][=C][Ring1][=Branch1][C][=Branch1][C][=O][O][C].[C][Branch1][Ring2][C][C][N][C][C@H1][Branch1][=Branch1][C][=Branch1][C][=O][O][N]"}]
