[{"from": "human", "value": "Create a molecule with the structure as the one described. The molecule is a 3-sn-phosphatidyl L-serine in which the phosphatidyl acyl groups at both positions 1 and 2 are specified as hexadecanoyl (palmitoyl). It has a role as a mouse metabolite. It is functionally related to a hexadecanoic acid. It is a conjugate acid of a 1,2-dihexadecanoyl-sn-glycero-3-phospho-L-serine(1-)."}, {"from": "gpt", "value": "[C][C][C][C][C][C][C][C][C][C][C][C][C][C][C][C][=Branch1][C][=O][O][C][C@H1][Branch2][Ring1][Branch1][C][O][P][=Branch1][C][=O][Branch1][C][O][O][C][C@@H1][Branch1][=Branch1][C][=Branch1][C][=O][O][N][O][C][=Branch1][C][=O][C][C][C][C][C][C][C][C][C][C][C][C][C][C][C]"}]
