Purine is adenine

WebAdenine is one of the purines. The two rings are formed by a 5-membered ring fused with a 6-membered ring. Conjugated double bonds are found between positions 1 and 6, 2 and 3, 4 and 5, 7 and 8. The Nitrogen atom at position 9 is covalently bonded to ribose or deoxyribose to form nucleosides called adenosine and deoxyadenosine respectively. http://www.bch.cuhk.edu.hk/vr_biomolecules/purine-and-pyrimidine-base.html
