Specification :

Fumaric acid is an organic acid widely found in nature. In humans and other mammals, Fumaric acid is a key intermediate in the tricarboxylic acid cycle for organic acid biosynthesis ( the KREBS cycle) . Fumaric acid is also an essential ingredient in plant life.
Fumaric acid is the strongest organic food acid in titratable acidity and in sourness.
Natural and synthetically produced Fumaric Acids have the same molecular structure. Bartek Fumaric Acid is made from N-Butane that is oxidised to Maleic acid that is then isomerized to Fumaric acid.
