Pyrimidines and Purines Pyrimidine and purine are the names of the parent compounds of two types of nitrogen- containing heterocyclic aromatic compounds. N N N N N NH PyrimidinePurine

Important Pyrimidines Pyrimidines that occur in DNA are cytosine and thymine. Cytosine and uracil are the pyrimidines in RNA. HNHNHNHN NHNHNHNHOO Uracil HNHNHNHN NHNHNHNHOO CH 3 Thymine HNHNHNHN NHNHNHNH NH2NH2NH2NH2 O Cytosine

Important Purines Adenine and guanine are the principal purines of both DNA and RNA. Adenine N N NH2NH2NH2NH2N NHNHNHNH GuanineO HNHNHNHN NHNHNHNH N N H2NH2NH2NH2N

Caffeine and Theobromine Caffeine (coffee) and theobromine (coffee and tea) are naturally occurring purines. Caffeine N NON N H3CH3CH3CH3C O CH 3 TheobromineO HNHNHNHN N N N O

Uridine and Adenosine Uridine and adenosine are pyrimidine and purine nucleosides respectively of D -ribofuranose. Uridine (a pyrimidine nucleoside) Adenosine (a purine nucleoside) N N N N HOCH 2 O OHHO NH2NH2NH2NH2

27.25 Nucleotides

Nucleotides Nucleotides are phosphoric acid esters of nucleosides.

Adenosine 5'-Monophosphate (AMP) Adenosine 5'-monophosphate (AMP) is also called 5'- adenylic acid. N N N N O OHHO NH2NH2NH2NH2 OCH 2 P HO O HO

Adenosine 5'-Monophosphate (AMP) Adenosine 5'-monophosphate (AMP) is also called 5'- adenylic acid. N N N N O OHHO NH2NH2NH2NH2 OCH 2 P HO O HO 1' 2'3' 4' 5'
