Difference Between Purines And Pyrimidines

Purines are heterocyclic aromatic organic compounds that are consist of a pyrimidine ring. this ring is fused in an imidazole ring. on the other hand, Pyrimidines are also heterocyclic aromatic organic compounds and are very similar to pyridine and benzene. they contain a ring with six members in which two nitrogen atoms exist on positions 1 and 3 of the six members ring. the basic difference Between Purines And Pyrimidines is that purines contain 2 carbon-nitrogen rings with 4 nitrogen atoms, their melting and boiling points are very high, synthesized by Traube purine, and during the catabolism, urine is produced while Pyrimidines have a ring of single carbon and nitrogen with 2 nitrogen atoms. their melting and boiling points are low and are synthesized by biginellibeta amino acids and carbon dioxide is produced in catabolism.
