Task: Please create a description for a molecule based on its representation.
SMILES: CCC1=C(C)/C(=C/c2[nH]c(Cc3[nH]c(/C=C4\NC(=O)C(C)=C4CC)c(C)c3CCC(=O)O)c(CCC(=O)O)c2C)NC1=O
Constraint: Answer the question with complete sentences.
Result: The molecule is a biladiene that is a homologue of bilirubin IXalpha (vinyl groups reduced to ethyl), a natural product of heme catabolism and the primary pigment of bile acid.
