Atomic structure
There is only one chemically distinct structure:
[*]O[C@H]1[C@H](O)[C@@H](CO[C@H]2O[C@H](CO[C@@H]3O[C@H](CO)[C@@H](O)[C@H](O)[C@H]3O)[C@@H](O)[C@H](O)[C@H]2O)O[C@@H](O[C@@H]2[C@@H](C(=O)O)O[C@@H](O[C@@H]3[C@@H](CO)O[C@@H](O[C@H]4[C@H](C)O[C@@H]([*])[C@H](O)[C@@H]4O)[C@H](O)[C@H]3O)C[C@H]2O)[C@@H]1O
