what is adenine
Adenine, C5H5N5 is a nitrogen-containing biological compound which can be found on DNA, RNA, nucleotides or nucleosides that plays a great role in cellular metabolism of organisms. It is also called purine which can be described as a six-membered (pyrimidine) ring fused with a five membered ring (imidazole). Both rings are heterocyclic. Some of its functions and roles are: (1) main component for genetic composition (2) used for protein synthesis (3) forms adenosine, which is a precursor of ATP. ATP is the primary energy source of living organism (4) plays a role in muscle contraction and intracellular signal transduction.
