Diphosphate

Adenosine diphosphate ADPdiphosphate, also known as adenosine diphosphate APPis an important organic compound in metabolism and is essential to the flow of energy in living cells, diphosphate. ADP consists of three important structural components: a sugar diphosphate attached to adenine and two phosphate groups diphosphate to the 5 carbon atom of ribose. AMP contains one fewer phosphate group. The cleavage of a phosphate group from ATP results in the coupling of energy to metabolic reactions and a by-product of ADP.

A number of pyrophosphate salts exist, such as disodium pyrophosphate Na 2 H 2 P 2 O 7 and tetrasodium pyrophosphate Na 4 P 2 O 7 , among others. Often pyrophosphates are called diphosphates. The parent pyrophosphates are derived from partial or complete neutralization of pyrophosphoric acid. Pyrophosphates are found in ATP and other nucleotide triphosphates, which are important in biochemistry. 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. This bond is also referred to as a high-energy phosphate bond. Pyrophosphoric acid is a tetraprotic acid, with four distinct p K a 's: [1].

Phosphate is everywhere in biochemistry. As we were reminded in the introduction to this chapter, our DNA is linked by phosphate:. The function of many proteins is regulated - switched on and off - by enzymes which attach or remove a phosphate group from the side chains of serine, threonine, or tyrosine residues. Countless diseases are caused by defects in phosphate transferring enzymes. As just one example, achondroplasia, a common cause of dwarfism, is caused by a defect in an enzyme whose function is to transfer a phosphate to a tyrosine residue in a growth-related signaling protein. Finally, phosphates are excellent leaving groups in biological organic reactions, as we will see many times throughout the remainder of this book.
