Fumaric acid, also known as E297 or fumarsaeure, belongs to the class of organic compounds known as dicarboxylic acids and derivatives. These are organic compounds containing exactly two carboxylic acid groups. Fumaric acid is a weakly acidic compound (based on its pKa). Fumaric acid exists in all living species, ranging from bacteria to humans. Within humans, fumaric acid participates in a number of enzymatic reactions. In particular, fumaric acid can be biosynthesized from L-malic acid; which is catalyzed by the enzyme fumarate hydratase, mitochondrial. In addition, fumaric acid can be biosynthesized from succinic acid through the action of the enzyme mutant succinate dehydrogenase. A butenedioic acid in which the C=C double bond has E geometry. In humans, fumaric acid is involved in the metabolic disorder called the glutaminolysis and cancer pathway. Fumaric acid is an odorless and sour tasting compound. Outside of the human body, Fumaric acid is found, on average, in the highest concentration within a few different foods, such as sweet cherries, star fruits, and milk (cow) and in a lower concentration in grape wines. Fumaric acid has also been detected, but not quantified in, several different foods, such as cow milks, apples, fishes, garden rhubarbs, and common sages. This could make fumaric acid a potential biomarker for the consumption of these foods. Fumaric acid is a potentially toxic compound. Fumaric acid, with regard to humans, has been found to be associated with several diseases such as rheumatoid arthritis, eosinophilic esophagitis, and lung cancer; fumaric acid has also been linked to several inborn metabolic disorders including 2-ketoglutarate dehydrogenase complex deficiency and fumarase deficiency.
