Task: Please generate a molecule SMILES based on the description.
Description: The molecule is a derivative of L-gulonic acid having a keto group at the 3-position. It has a role as an Escherichia coli metabolite. It is a ketoaldonic acid and a hexonic acid. It derives from a L-gulonic acid. It is a conjugate acid of a 3-dehydro-L-gulonate.
Result: O=C(O)[C@@H](O)C(=O)[C@H](O)[C@@H](O)CO
