| Questions And Answer | Back Directory | [Discovery]
Itaconic acid was discovered by Baup in 1837 as a product of the pyrolytic distillation of citric acid. The name itaconic was devised as an anagram of aconitic. Itaconic acid is formed in the fermentation of some sugars. In 1929, Kinoshita first showed the acid as a metabolic product of Aspergillus itaconicus.
| [Source]
Itaconic acid is formed by the cytosolic enzyme aconitate decarboxylase from cis-aconitic acid. Another biosynthetic pathway from pyruvate through citramalic acid, citraconic acid, and itartaric acid also results in itaconic acid. |
