Task: Please create a text description for a molecule based on its representation.
SMILES: C=C(C)[C@@H]1CC[C@]2(COC(=O)CC(C)C(=O)O)CC[C@]3(C)[C@H](CC[C@@H]4[C@@]5(C)CC[C@H](OC(=O)CC(C)C(=O)O)C(C)(C)[C@@H]5CC[C@]43C)[C@@H]12
Constraint: Answer the question with complete sentences.
Result: The molecule is a pentacyclic triterpenoid that is betulin acylated at positions O-3 and O-28 by 3-carboxybutanoyl groups. It is isolated from Syzygium claviflorum. It has a role as a metabolite. It derives from a betulin.
