- Not to be confused with meconic acid, an unrelated dicarboxylic acid
Muconic acid is a dicarboxylic acid. There are three isomeric forms designated trans,trans-muconic acid, cis,trans-muconic acid, and cis,cis-muconic acid which differ by the geometry around the double bonds.
trans,trans-Muconic acid is a metabolite of benzene in humans. The determination of its concentration in urine is therefore used as a biomarker of occupational or environmental exposure to benzene. Synthetically, trans,trans-muconic acid can be prepared from adipic acid.
cis,cis-Muconic acid is produced by some bacteria by the enzymatic degradation of various aromatic chemical compounds.
