Pyrophosphatase (or inorganic pyrophosphatase) is an enzyme that converts one molecule of pyrophosphate to two phosphate ions. This highly exergonic reaction (about -34KJ change in free energy) can be coupled to unfavorable biochemical transformations in order to drive these transformations to completion, as in Lipid synthesis and other biochemical transformations.
