Task: Please create a description for a molecule based on its representation.
Molecule SMILES: O=C(O)[C@@H](O)[C@@H]1OC[C@H](O)[C@H]1O
Constraint: Answer the question with complete sentences.
Result: The molecule is an anhydrohexose obtained by formation of a ring across the 3 and 6 positions of L-galactonic acid It has a role as a marine metabolite. It is an anhydrohexose and a carbohydrate acid. It derives from a L-galactonic acid.
