Binary acids are acids that consist of two elements, usually hydrogen and one of the halogens. Oxyacids are acids that contain hydrogen, oxygen, and a third element (usually a nonmetal). uMany polyatomic ions are produced by the loss of hydrogen ions from oxyacids. Some examples include: sulfate from sulfuric acid, nitrate from nitric acid, and phosphate from phosphoric acid.
Fumaric acid or trans-butenedioic acid is the chemical compound with the formula HO 2 CCH=CHCO 2 H. It is produced in eukaryotic organisms from succinate in complex 2 of the electron transport chain via the enzyme succinate dehydrogenase. It is one of two isomeric unsaturated dicarboxylic acids, the other being maleic acid. In fumaric acid the carboxylic acid groups are trans (E) and in maleic acid they are cis (Z). Fumaric acid has a fruit-like taste.
