Task: Please give me a SMILES based on the description below.
Description: 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.
Result: 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
