Chemical Information
FooDB NamePyrophosphate
DescriptionIn chemistry, the anion, the salts, and the esters of pyrophosphoric acid are called pyrophosphates. The anion is abbreviated PPi and is formed by the hydrolysis of ATP into AMP in cells. This hydrolysis is called pyrophosphorolysis. The pyrophosphate anion has the structure P2O74-, and is an acid anhydride of phosphate. It is unstable in aqueous solution and rapidly hydrolyzes into inorganic phosphate [HMDB]. Pyrophosphate is found in many foods, some of which are small-leaf linden, calabash, swamp cabbage, and lemon.
