triphosphate
Phosphate group trio
Triphosphate refers to a chemical group containing three linked phosphate units.
It appears most famously in ATP (adenosine triphosphate), the molecule that stores and transfers energy in living cells.
The three phosphate bonds hold significant energy—when one breaks off, it powers cellular work.
The reaction releases energy by converting ATP to ADP.
