[{"from": "human", "value": "Generate a molecule based on the given description. The molecule is a phosphatidylcholine 32:0 in which the 1- and 2-acyl groups are specified as hexadecanoyl (palmitoyl). A synthetic phospholipid used in liposomes and lipid bilayers to study biological membranes. It is also a major constituent of pulmonary surfactants. It has a role as a surfactant and a mouse metabolite. It is a phosphatidylcholine 32:0 and a 1-acyl-2-hexadecanoyl-sn-glycero-3-phosphocholine. It is functionally related to a hexadecanoic acid."}, {"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-1][O][C][C][N+1][Branch1][C][C][Branch1][C][C][C][O][C][=Branch1][C][=O][C][C][C][C][C][C][C][C][C][C][C][C][C][C][C]"}]
