Task: Please create a text description for a molecule based on its representation.
SMILES: O=C(O)C1=C[C@H](O)[C@@H](O)[C@@H](O)O1
Constraint: Answer the question with complete sentences.
Result: The molecule is a hexuronic acid that is 3,4-dihydro-2H-pyran-6-carboxylic acid substituted by a hydroxy group at each of the positions 2, 3, and 4 (the 2S,3R,4S-diastereoisomer). It is a conjugate acid of a 4-deoxy-beta-L-threo-hex-4-enopyranuronate.
