Important salts include disodium pyrophosphate and tetrasodium pyrophosphate.
Disodium pyrophosphate or sodium acid pyrophosphate (SAPP) is an inorganic compound consisting of sodium cations and pyrophosphate anion.

Phosphate

The term pyrophosphate is also the name of esters formed by the condensation of a phosphorylated biological compound with inorganic phosphate, as for dimethylallyl pyrophosphate.
At elevated temperatures in the solid state, phosphates can condense to form pyrophosphates.

Adenosine monophosphate

It is formed by the hydrolysis of ATP into AMP in cells.
AMP can also be formed by hydrolysis of ATP into AMP and pyrophosphate:

High-energy phosphate

phosphoanhydridehigh energy phosphatehigh-energy
This bond is also referred to as a high-energy phosphate bond.
High-energy phosphate bonds are pyrophosphate bonds, acid anhydride linkages formed by taking phosphoric acid derivatives and dehydrating them.

Nucleoside triphosphate

dNTPnucleotide triphosphateNTP
Pyrophosphorolysis is the reverse of the polymerization reaction in which pyrophosphate reacts with the 3′-nucleosidemonophosphate (NMP or dNMP), which is removed from the oligonucleotide to release the corresponding triphosphate (dNTP from DNA, or NTP from RNA).
These enzymes covalently link the free -OH group on the 3’ carbon of a growing chain of nucleotides to the α-phosphate on the 5’ carbon of the next (d)NTP, releasing the β- and γ-phosphate groups as pyrophosphate (PPi).

Hydrolysis

It is formed by the hydrolysis of ATP into AMP in cells.
The ATP molecule contains pyrophosphate linkages (bonds formed when two phosphate units are combined together) that release energy when needed.
