  • Adenosine triphosphate (ATP) is a nucleotide with three phosphates. The ATP is produced by the addition of phosphorous to nucleoside adenosine.
  • The first phosphate is attached by an ester bond. This bond is a normal covalent bond and not a high energy bond.
  • The two-terminal phosphates are bonded by high energy acid anhydride bonds.

Thus one molecule of ATP contains two high energy bonds.
