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