Metabolite Identification
Common NamePyrophosphate
DescriptionPyrophosphates are the anions, the salts, and the esters of pyrophosphoric acid. 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
