Task: Please create a text description for a molecule based on its representation.
Molecule SMILES: CC(=O)N[C@H]1[C@H]([C@H](O)[C@H](O)CO)O[C@@](O[C@H](CO)[C@@H](O)[C@@H]2O[C@@](O)(C(=O)O)C[C@H](O)[C@H]2NC(C)=O)(C(=O)O)C[C@@H]1O
Constraint: Answer the question with complete sentences.
Result: The molecule is alpha-Neu5Ac-(2->8)-Neu5Ac in which the configuration at the anomeric carbon atom of the residue at the reducing end is alpha It has a role as an epitope.
