Metabolite Identification
Common NameMesaconic acid
DescriptionCitraconic acid, also known as 2-methylmaleate 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. Citraconic acid exists as a solid, very hydrophobic, practically insoluble (in water), and relatively neutral molecule. Citraconic acid exists in all living organisms, ranging from bacteria to humans.
