'''Purino''' estas nitrogenhava heterocikla organika kombinaĵo, kiu konsistas de unu [[pirimidino|pirimidina]] ringo kaj unu [[imidazolo|imidazola]] ringo. Purinoj kaj pirimidinoj estas la du klasoj de [[nitrogena bazo|nitrogenaj bazoj]]. Tiuj bazoj make up a crucial part of both deoxyribonucleotides and ribonucleotides, and the basis for the universal genetic code.

'''Purine''' ('''1''') is a [[heterocyclic compound|heterocyclic]] [[aromatic]] [[organic compound]], consisting of a [[pyrimidine]] ring fused to an [[imidazole]] ring. Purines and pyrimidines make up the two groups of [[nitrogenous bases]]. These bases make up a crucial part of both deoxyribonucleotides and ribonucleotides, and the basis for the universal genetic code.
 
La termino '''purino''' ankaŭ signifas la substituitaj purinoj kaj siaj [[tautomero|tautomeroj]].
The general term '''purines''' also refers to substituted purines and their [[tautomer]]s.
 
La purino estas la plej distribuita nitrogenhava [[heterocikla]] kombinaĵo en la naturo.
The purine is the most widely distributed nitrogen-containing [[heterocycle]] in nature.<ref>Rosemeyer, H. ''Chemistry & Biodiversity'' '''2004''', ''1'', 361.</ref>
