Task: Please create a description for a molecule.
Molecule SMILES: O[C@H]1[C@@H]2OC[C@H](O[C@H]1O)[C@H]2O
Constraint: Answer the question with full sentences.
Result: The molecule is an anhydrohexose obtained by formation of a ring across the 3 and 6 positions of alpha-L-galactopyranose. It has a role as a marine metabolite. It is an anhydrohexose and a bridged compound. It derives from an alpha-L-galactose.
