Task: Please create a text description for a molecule based on its representation.
SMILES: C[C@H]1C[C@@H](CO)[C@H](O)O[C@@H]2C[C@@H]3O[C@@H]4[C@@H](C)[C@H](C)[C@@]5(CCCO5)O[C@H]4[C@@H](O)[C@H](C)[C@H]3O[C@H]2C1
Constraint: Answer the question with full sentences.
Result: The molecule is a polycyclic ether comprising a linear sequence of sequence of four trans-fused oxacycles and one spiro-fused tetrahydrofuran ring. It has a role as a hapten. It is a polycyclic ether and an organic heteropentacyclic compound.
