Task: Please create a text description for a molecule based on its representation.
Molecule SMILES: CC(=O)[C@@]1(O)CC[C@H]2[C@@H]3CC=C4CC(=O)CC[C@]4(C)[C@H]3CC[C@@]21C
Constraint: Answer the question with complete sentences.
Result: The molecule is a C21-steroid that is pregnane which contains a double bond between positions 5 and 6 and is substituted by oxo groups at positions 3 and 20 as well as a hydroxy group at position 17. It is a 20-oxo steroid, a 3-oxo-Delta(5)-steroid, a C21-steroid, a 17alpha-hydroxy steroid, a 17alpha-hydroxy-C21-steroid and a tertiary alpha-hydroxy ketone. It derives from a hydride of a pregnane.
