Task: Please create a description for a molecule.
SMILES: O=C(O)[C@@]1(O[C@H](CO)[C@@H](O)[C@@H]2O[C@@](O)(C(=O)O)C[C@H](O)[C@H]2O)C[C@H](O)[C@@H](O)[C@H]([C@H](O)[C@@H](CO)O[C@]2(C(=O)O)C[C@H](O)[C@@H](O)[C@H]([C@H](O)[C@H](O)CO)O2)O1
Constraint: Answer the question with complete sentences.
Result: The molecule is an oligosaccharide consisting of deamino-alpha-neuraminyl residues linked (2->8) (degree of polymerisation = 2--7; average degree of polymerisation ~ 3). It derives from a deamino-alpha-neuraminic acid.
