Adenosine diphosphate, abbreviated ADP, is a nucleotide. It is an ester of pyrophosphoric acid with the nucleoside adenosine. ADP consists of the pyrophosphate group, the pentose sugar ribose, and the nucleobase adenine.

adenosine diphosphate (ADP)
A nucleotide consisting of adenine, ribose, and two phosphate groups; formed by the removal of one phosphate from an ATP molecule.
adenosine monophosphate (AMP) ...
adenosine diphosphate (ADP) Lower energy form of ATP, having two (instead of the three in ATP) phosphhate groups attached to the adenine base and ribose sugar. PICTURE ...
Adenosine diphosphate
ATPases are a class of enzymes that catalyze the decomposition of adenosine triphosphate (ATP) into adenosine diphosphate (ADP) and a free phosphate ion.
adenosine diphosphate (ADP) The building block for ATP; by adding a terminal phosphate group and a large amount of energy, ATP can be formed.
ADP is adenosine diphosphate. Pi is inorganic phosphate. [structure]
For this reason, this bond is known as a "high-energy" bond and is depicted in the figure by a wavy red line. (The bond between the first and second phosphates is also "high-energy".
b) in English Adenosine Triphosphate produces Adenosine diphosphate + energy + inorganic Phosphate ...
Produced by adding Pi to ADP → phosphorylation
Breaks down to ADP (adenosine diphosphate) and Pi (inorganic phosphate ion) by hydrolysis
ATP is useful as an immediate energy source/carrier because ...
(ATP) The major source of usable energy in cell metabolism; composed of adenine, ribose, and three phosphate groups. On hydrolysis, ATP loses one phosphate and one hydrogen to become adenosine diphosphate (ADP) and releases energy in the process.
