Task: Please create a description for a molecule based on its representation.
SMILES: CC(C)CCC[C@@](C)(O)[C@@]1(O)CC[C@H]2[C@@H]3CC=C4C[C@@H](O)CC[C@]4(C)[C@H]3CC[C@@]21C
Constraint: Answer the question with complete sentences.
Result: The molecule is an oxysterol that is cholesterol substituted by hydroxy groups at positions 17 and 20 (the 20R-stereoisomer). It has a role as a human metabolite and a mouse metabolite. It is a 17alpha-hydroxy steroid, a 20-hydroxy steroid, an oxysterol and a 3beta-hydroxy-Delta(5)-steroid. It derives from a cholesterol.
