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