[{"from": "human", "value": "Design a molecule that meets the criteria outlined in the description. The molecule is the conjugate base of gamma-amino-beta-hydroxybutyric acid arising from deprotonation of the carboxy group. It is a hydroxy monocarboxylic acid anion and a gamma-amino acid anion. It is functionally related to a butyrate. It is a conjugate base of a gamma-amino-beta-hydroxybutyric acid and a gamma-amino-beta-hydroxybutyric acid zwitterion."}, {"from": "gpt", "value": "[C][Branch1][#Branch1][C][Branch1][Ring1][C][N][O][C][=Branch1][C][=O][O-1]"}]
