Task: Please create a text description for a molecule based on its representation.
Molecule SMILES: 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]2O)[C@@H]([C@H](O)CO)O1
Constraint: Answer the question with full sentences.
Result: The molecule is a linear trisaccharide comprising two L-glycero-alpha-D-manno-heptose residues and a 3-deoxy-alpha-D-manno-oct-2-ulosonic acid (2-keto-3-deoxy-alpha-D-mannooctanoic acid, alpha-Kdo) residue in a (1->3), (1->5) sequence.
