Task: Please create a description for a molecule.
Molecule SMILES: CC(=O)N[C@@H]1[C@@H](O)[C@H](O[C@@H]2O[C@H](CO)[C@H](O[C@H]3O[C@H](CO)[C@H](O)[C@H](O)[C@H]3O)[C@H](O[C@H]3O[C@H](CO)[C@H](O)[C@H](O)[C@H]3O)[C@H]2O)[C@@H](CO)O[C@H]1O
Constraint: Answer the question with full sentences.
Result: The molecule is a branched amino tetrasaccharide comprising an alpha-D-galactosyl-(1->3)-beta-D-galactopsyl-(1->4)-N-acetyl-beta-D-glucosamine linear trisaccharide, the central galactoside residue of which is linked to a further alpha-D-galactose residue via an alpha(1->4) glycosidic bond. It has a role as an epitope. It is an amino tetrasaccharide and a glucosamine oligosaccharide.
