User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a 1-acyl-2-octadecanoyl-sn-glycero-3-phosphate(2-) in which the 1-acyl group is specified as hexadecanoyl (palmitoyl); major species at pH 7.3. It is a conjugate base of a 1-hexadecanoyl-2-octadecanoyl-sn-glycero-3-phosphate.
Assistant: This is a molecule that fits your description: CCCCCCCCCCCCCCCCCC(=O)O[C@H](COC(=O)CCCCCCCCCCCCCCC)COP(=O)([O-])[O-]
