Task: Please create a text description for a molecule.
Molecule SMILES: C=CC1=C(C)C(/C=c2\[nH]/c(=C\c3[nH]c(C(=O)c4[nH]c(C=O)c(C)c4C=C)c(C)c3CCC(=O)[O-])c(CCC(=O)[O-])c2C)=NC1=O
Constraint: Answer the question with complete sentences.
Result: The molecule is a linear tetrapyrrole anion obtained by deprotonation of the two carboxy groups of mycobilin a; major species at pH 7.3. It is a dicarboxylic acid dianion and a linear tetrapyrrole anion. It is a conjugate base of a mycobilin a.
