Task: Please create a description for a molecule.
Molecule SMILES: O=C1O[C@H]([C@@H](O)CO)[C@@H](O)[C@@H]1O
Constraint: Answer the question with full sentences.
Result: The molecule is a galactonolactone that is 3,4-dihydroxydihydrofuran-2(3H)-one substituted by a 1,2-dihydroxyethyl group at position 5 (the 3S,4S,5R-isomer). It has a role as a plant metabolite. It derives from a L-galactonic acid.
