Pyrophosphate

pyrophosphate

(Science: chemistry) Two phosphate groups linked by esterification. Released in many of the synthetic steps involving nucleotide triphosphates (e.g. Protein and nucleic acid elongation). Rapid cleavage by enzymes that have high substrate affinity ensures that these reactions are essentially irreversible.
