[{"from": "human", "value": "Based on the given information, design a molecule that meets the desired specifications. The molecule is dianion of L-erythrulose 1-phosphate arising from deprotonation of the phosphate OH groups; major species at pH 7.3. It is a conjugate base of a L-erythrulose 1-phosphate. It is an enantiomer of a D-erythrulose 1-phosphate(2-)."}, {"from": "gpt", "value": "[C][Branch2][Ring1][Ring1][C@@H1][Branch1][#C][C][=Branch1][C][=O][C][O][P][=Branch1][C][=O][Branch1][C][O-1][O-1][O][O]"}]
