The true measure of an appraisalâwhether a gem, jewelry, or a watchâis a combination of sophisticated laboratory technology, and expertise in interpreting the test results.
ATP works by losing the endmost phosphate group when instructed to do so by an enzyme. This reaction releases a lot of energy, which the organism can then use to build proteins, contact muscles, etc. The reaction product is adenosine diphosphate (ADP), and the phosphate group either ends up as orthophosphate (HPO 4) or attached to another molecule (e.g. an alcohol).
The Adenosine triphosphate (ATP) molecule is the nucleotide known in biochemistry as the molecular currency of intracellular energy transfer; that is, ATP is able to store and transport chemical energy within cells. ATP also plays an important role in the synthesis of nucleic acids. For 3-D Structure of this image using Jsmol Click here . Image: Molecular Structure of ATP. Energy is released by hydrolysis of the third phosphate group. After this third phosphate group is released, the resulting ADP (adenosine diphosphate) can absorb energy and regain the group, thus regenerating an ATP molecule; this allows ATP to store energy like a rechargeable battery.
