[{"from": "human", "value": "Design a molecule that meets the criteria outlined in the description. The molecule is a carbohydrate acid derivative that consists of D-glucuronic acid having a 6-O-sulfo-N-acetyl-alpha-D-glucosaminyl residue attached at position 4. An intermediate glycan in the degradation of heparan sulfate. It has a role as a mouse metabolite. It is an amino disaccharide, a carbohydrate acid derivative and an oligosaccharide sulfate."}, {"from": "gpt", "value": "[C][C][=Branch1][C][=O][N][C@@H1][C@H1][Branch2][Ring2][S][C@@H1][Branch2][Ring2][O][C@H1][Branch2][Ring1][=N][O][C@@H1][Ring1][=Branch1][O][C@H1][C@@H1][Branch2][Ring1][C][C@H1][Branch1][=C][C][Branch1][#Branch2][O][C@@H1][Ring1][=Branch1][C][=Branch1][C][=O][O][O][O][O][C][O][S][=Branch1][C][=O][=Branch1][C][=O][O][O][O]"}]
