Task: Please create a description for a molecule based on its representation.
Molecule SMILES: C[C@@H]1O[C@@H](O[C@H]2[C@H](O[C@H]3[C@H](O)[C@@H](O)[C@H](O)O[C@@H]3CO)O[C@H](CO)[C@H](O)[C@@H]2O[C@H]2O[C@H](CO)[C@H](O)[C@H](O)[C@H]2O)[C@@H](O)[C@H](O)[C@@H]1O
Constraint: Answer the question with full sentences.
Result: The molecule is a branched tetrasaccharide with a structure consisting of an alpha-galactosyl-(1->3)-beta-galactosyl-(1->4)-glucose backbone, to the subterminal galactose of which is alpha(1->2)-linked a fucosyl residue. It has a role as an epitope.
