Task: Please create a text description for a molecule.
SMILES: C=CCO[C@]1(C(=O)O)C[C@@H](O[C@]2(C(=O)O)C[C@@H](O)[C@@H](O)[C@@H]([C@H](O)CO)O2)C=C([C@H](O)CO)O1
Constraint: Answer the question with full sentences.
Result: The molecule is a disaccharide derivative consisting of a 3-deoxy-alpha-D-manno-oct-2-ulopyranonosyl unit joined via an alpha-(2->4)-linkage to a 5,6-dehydro-3-deoxy-alpha-D-manno-oct-2-ulopyranonosyl unit with an O-allyl group at the anomeric centre.
