A fumarate is a salt or ester of the
organic compound fumaric acid, a dicarboxylic acid. Its formula is C4H4O44-
A precursor to L-malate in the Krebs tricarboxylic acid cycle. It is formed
by the oxidation of adenylsuccinate by succinate dehydrogenase.
Fumarate is converted by fumarase to malate. In simple fumarate is used by
cells to produce Energy (ATP) from food. Fumarate is also a byproduct of the
urea cycle.
