|Section2= |Section3= }} 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.〔''Organic Syntheses'', Coll. Vol. 3, p.623 (1955); Vol. 26, p.57 (1946). (Online copy )〕 ''cis,cis''-Muconic acid is produced by some bacteria by the enzymatic degradation of various aromatic chemical compounds. The bioproduction of muconic acid is of interest because of its potential use as a platform chemical for the production of several valuable consumer bioplastics including nylon-6,6, polyurethane, and polyethylene terephthalate (PET). ==See also== * Dicarboxylic acid * 2-Aminomuconic acid 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Muconic acid」の詳細全文を読む スポンサード リンク
