Task: Please create a description for a 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](O[C@@H]3O[C@H](CO)[C@@H](O)[C@H](O[C@@H]4O[C@H](CO)[C@H](O)[C@H](O)[C@H]4O)[C@H]3NC(C)=O)[C@H]2O)[C@@H](CO)O[C@H]1O
Constraint: Answer the question with complete sentences.
Result: The molecule is a tetrasaccharide comprising residues of galactose, N-acetylglucosamine, galactose and N-acetylglucosamine units in a linear sequence, joined sequentially via beta(1->3), beta(1->3), and beta(1->4) linkages. beta-D-Gal-(1->3)-beta-D-GlcNAc-(1->3)-beta-D-Gal-(1->4)-D-GlcNAc with beta-configuration at the anomeric centre of the reducing-end N-acetylglucosamine residue. It has a role as an epitope.
