Task: Please create a text description for a molecule based on its representation.
SMILES: C=CC1=C(C)C(/C=c2\[nH]/c(=C\c3[nH]c(/C=C4\NC(=O)C(C)=C4CCC(=O)[O-])c(CCC(=O)[O-])c3C)c(C)c2C=C)=NC1=O
Constraint: Answer the question with full sentences.
Result: The molecule is a linear tetrapyrrole anion obtained by deprotonation of the two carboxy groups of biliverdin beta; major species at pH 7.3. It is a dicarboxylic acid dianion and a linear tetrapyrrole anion. It is a conjugate base of a biliverdin beta.
