User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is a heparan sulfate composed of a backbone of repeating alpha-L-iduronosyl-(1->4)-N-sulfonyl-alpha-D-glucosamine units joined by (1->4)-linkages. It has a role as a mouse metabolite. It is a member of heparan sulfates and a member of iduronic acids. It derives from a L-idopyranuronic acid. It is a conjugate acid of a heparosan N-sulfate L-iduronate polyanion.
Assistant: This is a molecule that fits your description: O=C(O)[C@@H]1O[C@@H](O[C@H]2[C@H](O)[C@@H](NS(=O)(=O)O)[C@@H](O)O[C@@H]2CO)[C@H](O)[C@@H](O)[C@@H]1O
