User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is an anionic phospholipid obtained by deprotonation of the free carboxy group of 1-hexadecyl-2-succinyl-sn-glycero-3-phosphocholine; major species at pH 7.3. It is an anionic phospholipid and a monocarboxylic acid anion. It is a conjugate base of a 1-hexadecyl-2-succinyl-sn-glycero-3-phosphocholine.
Assistant: This is a molecule that fits your description: CCCCCCCCCCCCCCCCOC[C@H](COP(=O)([O-])OCC[N+](C)(C)C)OC(=O)CCC(=O)[O-]
