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[C@@H]2[C@H](O)[C@@H](O)C(O)O[C@@H]2C(=O)O)O1
Constraint: Answer the question with complete sentences.
Result: The molecule is a D-galacturonic acid having a 4-deoxy-alpha-L-threo-hex-4-enopyranosyluronic acid moiety attached at the 4-position. It is a conjugate acid of a 4-(4-deoxy-beta-D-gluc-4-enosyluronate)-D-galacturonate(2-).
