Task: Please generate a molecule SMILES based on the text description below.
Description: The molecule is a linear trisaccharide consisting of alpha-KDN, beta-D-galactose and D-glucosamine residues linked sequentially (2->3) and (1->4). It has a role as an epitope.
Result: O=C(O)[C@@]1(O[C@H]2[C@@H](O)[C@@H](CO)O[C@@H](O[C@H]3[C@H](O)[C@@H](O)C(O)O[C@@H]3CO)[C@@H]2O)C[C@H](O)[C@@H](O)[C@H]([C@H](O)[C@H](O)CO)O1
