User: I'm looking for the SMILES of a molecule that can be described by:
The molecule is a peptide anion obtained by deprotonation of the four carboxy groups of Ac-Asp-Glu-Glu; major species at pH 7.3. It is a conjugate base of an Ac-Asp-Glu-Glu.
Assistant: This is a molecule that fits this description: CC(=O)N[C@@H](CC(=O)[O-])C(=O)N[C@@H](CCC(=O)[O-])C(=O)N[C@@H](CCC(=O)[O-])C(=O)[O-]
