Task: Please create a text description for a molecule based on its representation.
Molecule SMILES: N[C@@H]1[C@@H](O)[C@H](O[C@@H]2O[C@H](C(=O)O)[C@@H](O)[C@H](O)[C@H]2O)[C@@H](CO)O[C@@H]1O
Constraint: Answer the question with full sentences.
Result: The molecule is a heparan composed of a backbone of repeating beta-D-glucuronosyl-(1->4)-alpha-D-glucosamine units joined by (1->4)-linkages. It derives from a D-glucopyranuronic acid. It is a tautomer of a heparosan D-glucuronic acid zwitterion.
