User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a linear amino tetrasaccharide composed of N-acetyl-beta-D-galactosamine, alpha-D-galactose, beta-D-galactose and N-acetyl-beta-D-galactosamine units joined by sequential (1->3)-, (1->4)- and (1->4)-linkages. It has a role as an epitope.
Assistant: This is a molecule that fits this description: 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]4O[C@H](CO)[C@H](O)[C@H](O)[C@H]4NC(C)=O)[C@H]3O)[C@H](O)[C@H]2O)[C@@H](CO)O[C@H]1O
