Task: Please create a text description for a molecule.
Molecule SMILES: O=C(O)C1O[C@@H](O)[C@@H](O)[C@@H](O)[C@@H]1O
Constraint: Answer the question with full sentences.
Result: The molecule is a linear copolymer macromolecule composed of homopolymeric blocks of 1->4-linked beta-D-mannuronic acid and alpha-L-guluronic acid residues, covalently linked together in different sequences or blocks. It has a role as a hematologic agent. It is a copolymer macromolecule, a heteroglycan and an exopolysaccharide. It is a conjugate acid of an alginate.
