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@]2(CO)C[C@@H](O)[C@@H](O)[C@@H]([C@H](O)CO)O2)[C@@H](O)[C@@H]([C@H](O)CO)O1
Constraint: Answer the question with complete sentences.
Result: The molecule is a disaccharide comprising 3-deoxy-alpha-D-manno-oct-2-ulopyranose (Kdo) having a 3-deoxy-alpha-D-manno-oct-2-ulopyranosyl (Kdo-CH2OH) residue attached at the 4-position. It has a role as an antigen.
