Atomic structure
There is only one chemically distinct structure:
[*]O[C@@H]1[C@@H](O)[C@H](C)O[C@@H](O[C@@H]2[C@@H](O)[C@H](O[C@@H]3[C@@H](O)[C@H](C)O[C@@H](O[C@@H]4[C@@H](O)[C@H](C)O[C@@H](O[C@@H]5[C@@H](O)[C@H](C)O[C@@H](O[C@@H]6[C@@H](O)[C@H](O)[C@@H](CO)O[C@@H]6[*])[C@@H]5O)[C@@H]4O)[C@@H]3O[C@H]3O[C@@H]4CO[C@@](C)(C(=O)O)O[C@@H]4[C@H](O)[C@H]3O)O[C@H](CO)[C@H]2O)[C@@H]1O
