Task: Please create a text description for a molecule.
Molecule SMILES: OC[C@H]1O[C@H](O[C@@H]2[C@@H](OC[C@H]3O[C@H](O)[C@@H](O)[C@@H](O[C@H]4O[C@H](CO)[C@@H](O)[C@H](O)[C@@H]4O[C@H]4O[C@H](CO)[C@@H](O)[C@H](O)[C@@H]4O)[C@@H]3O)O[C@H](CO)[C@@H](O)[C@@H]2O)[C@@H](O)[C@@H](O)[C@@H]1O
Constraint: Answer the question with full sentences.
Result: The molecule is a mannopentaose comprised of a chain of three alpha-D-mannose residues linked (1->2) and (1->3), with a further two-D-mannose-residue (1->2)-linked unit linked (1->6) to the mannose residue at the reducing end. It has a role as an epitope.
Task: Please create a {#text |!}description for a molecule{# based on its representation|!}.
{#Molecule |!}{SMILES__description}: {SMILES#}
Constraint: Answer the question with {#full|complete!} sentences.
Result: {description#}
