User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a linear pentasaccharide consisting of a beta-D-galactose residue, three L-glycero-alpha-D-manno-heptose residues and (at the reducing end) a 3-deoxy-alpha-D-manno-oct-2-ulopyranosonic acid (Kdo) residue linked sequentially (1->2), (1->2), (1->3) and (1->5); the structure is that of the pentasaccharide epitope from Haemophilus influenzae MAHI 4. It has a role as an epitope.
Assistant: This is a molecule that fits this description: O=C(O)[C@@]1(O)C[C@@H](O)[C@@H](O[C@H]2O[C@H]([C@@H](O)CO)[C@@H](O)[C@H](O[C@H]3O[C@H]([C@@H](O)CO)[C@@H](O)[C@H](O)[C@@H]3O[C@H]3O[C@H]([C@@H](O)CO)[C@@H](O)[C@H](O)[C@@H]3O[C@@H]3O[C@H](CO)[C@H](O)[C@H](O)[C@H]3O)[C@@H]2O)[C@@H]([C@H](O)CO)O1
