Task: Please give me a SMILES based on the description.
Description: The molecule is a carbohydrate lactone obtained by intramolecular condensation of the 6-carboxy group with the 3-hydroxy group of alpha-mannofuranuronic acid. It has a role as a metabolite. It is a furofuran, a gamma-lactone and a carbohydrate lactone.
Result: O=C1O[C@@H]2[C@H](O)[C@@H](O)O[C@@H]2[C@H]1O
