Metabolite Identification
Common Name2-Methylmaleate
Description2-Methylmaleate, also known as citraconic acid or methylmaleic acid, belongs to the class of organic compounds known as methyl-branched fatty acids. These are fatty acids with an acyl chain that has a methyl branch. Usually, they are saturated and contain only one or more methyl group. However, branches other than methyl may be present. 2-Methylmaleate is a dicarboxylic acid consisting of maleic acid having a methyl substituent at the 2-position. 2-Methylmaleate exists as a white solid. It is the cis-isomer of mesaconic acid and is one of the pyrocitric acids formed upon the heating of citric acid. 2-Methylmaleate has been detected in the urine of both normal and fasting individuals (PMID: 6778884 ). 2-Methylmaleate is also elevated in the urine of individuals with methylmalonic acidaemia who have suffered ketotic attacks (PMID: 116077 ). Altered serum levels of 2-methylmaleate have been detected in patients with primary biliary cholangitis (PMID: 28400566 ).
