[{"from": "human", "value": "Create a molecule that satisfies the conditions outlined in the description. The molecule is a linear amino trisaccharide comprising an alpha-N-glycoloylneuraminyl residue (2->3)-linked to a beta-D-galactosyl residue, which is in turn linked (1->4) to N-acetyl-beta-D-glucosamine. It has a role as an epitope. It is an amino trisaccharide and a glucosamine oligosaccharide."}, {"from": "gpt", "value": "[C][C][=Branch1][C][=O][N][C@@H1][C@H1][Branch2][=Branch1][=C][C@@H1][Branch1][O][C@H1][Branch1][=Branch1][O][C@H1][Ring1][=Branch1][O][C][O][O][C@H1][C@@H1][Branch2][Branch1][#Branch2][C@H1][Branch1][=N][C@H1][Branch1][=Branch2][C@H1][Branch1][Ring2][O][Ring1][=Branch1][C][O][O][O][C@@][Branch2][Ring1][P][C][C@@H1][Branch2][Ring1][O][C@H1][Branch1][P][C@@H1][Branch1][Ring2][O][Ring1][=Branch1][C@@H1][Branch1][#Branch1][C@@H1][Branch1][Ring1][C][O][O][O][N][C][=Branch1][C][=O][C][O][O][C][=Branch1][C][=O][O][O][O]"}]
