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).
ATP consists of adenosine â composed of an adenine ring and a ribose sugar â and three phosphate groups (triphosphate). The phosphoryl groups, starting with the group closest to the ribose, are referred to as the alpha (Î±), beta (Î²), and gamma (Î³) phosphates.
