User: I want to create a SMILES.
Assistant: This sounds very interesting. Should it be a special one?
User: Yes, the molecule can be described as:
The molecule is a polyanionic polymer obtained by deprotonation of the carboxy groups of alpha-D-galacturonosyl-[(1->2)-alpha-L-rhamnosyl-(1->4)-alpha-D-galacturonosyl]n; major species at pH 7.3. It is a carbohydrate acid anion and a polyanionic polymer.
Assistant: Ok, this SMILES fits your description: C[C@@H]1O[C@@H](O[C@@H]2[C@H](O)[C@@H](O)[C@@H](O)O[C@@H]2C(=O)[O-])[C@H](O[C@H]2O[C@H](C(=O)[O-])[C@H](O)[C@H](O)[C@H]2O)[C@H](O)[C@H]1O
