[{"from": "human", "value": "Generate a molecule based on the given description. The molecule is an amino disaccharide consisting of s-acetamido-2-deoxy-beta-D-galactopyranose and beta-D-galactopyranose residues joined in sequence by a (1->4) glycosidic bond. It is a member of acetamides, an amino disaccharide and a glycosylgalactose derivative. It is functionally related to a N-acetyl-beta-D-galactosamine and a beta-D-galactose."}, {"from": "gpt", "value": "[C][C][=Branch1][C][=O][N][C@@H1][C@H1][Branch2][Ring2][Ring2][C@H1][Branch2][Ring1][#C][C@H1][Branch2][Ring1][=Branch2][O][C@H1][Ring1][=Branch1][O][C@H1][C@H1][Branch1][=C][O][C@H1][Branch1][=Branch2][C@@H1][Branch1][Branch1][C@H1][Ring1][=Branch1][O][O][O][C][O][C][O][O][O]"}]
