GENERAL
DESCRIPTION AND APPLICATIONS |
Purine
is a heterocyclic compound featured by a fused pyrimidine and
imidazole rings composed of carbon and nitrogen atoms. The
simplest one is purine itself and the two major purines are
adenine(6-Aminopurine) and guanine(2-Amino-6-hydroxypurine).
Other important purines are caffeine, uric acid, theobromine,
and theophylline. Purine and its derivatives are biologically
important components of nucleic acids (DNA, RNA) and
coenzymes. |

GENERAL
DESCRIPTION OF NUCLEOSIDE |
Ribose
is a pentose (five-carbon sugar) that is a component of the
ribonucleic acid (RNA), where it alternates with phosphate
groups to form the 'back-bone' of the RNA polymer and binds to
nitrogenous bases. Ribose phosphates are components of the
nucleotide coenzymes and are utilized by microorganisms in the
synthesis of the amino acid histidine. Its close relative,
deoxyribose, is a constituent of deoxyribonucleic acid (DNA),
where it alternates with phosphate groups to form the
'back-bone' of the DNA polymer and binds to nitrogenous bases.
The presence of deoxyribose instead of ribose is one
difference between DNA and RNA. Ribose has one more oxygen
atom in its molecule than deoxyribose. Ribose has a five
member ring composed of four carbon atoms and one oxygen.
Hydroxyl groups are attached to three of the carbons. The
other carbon and a hydroxyl group are attached to one of the
carbon atoms adjacent to the oxygen. In dexoyribose, the
carbon furthest from the attached carbon is stripped of the
oxygen atom in what would be a hydroxyl group in ribose. The
sugar (ribose or deoxyribose) molecules in the nucleic acid
are all oriented in the same direction. Their carbon atoms are
numbered: the 5' carbon atom is always on the side of the
sugar molecule that faces the leading end, while the 3' carbon
atom always faces the tail end. Nucleotide is the structural
unit of a nucleic acid. A nucleotide consists of either a
nitrogenous heterocyclic base (purine or pyrimidine) , a
pentose sugar (ribose or deoxyribose) and a phosphate group
attached at the 5' position on the sugar. A nucleoside
consists of only a pentose sugar linked to a purine or
pyrimidine base, without a phosphate group. Purine bases are
Adenine, Guanine and Hypoxanthine (examples of purine
nucleosides are Adenosine, 2'-Deoxyadenosine, Guanosine,
2'-Deoxyguanosine, Inosine, 2'-Deoxyinosine). Pyrimidine bases
are Cytosine, Thymine, and Uracil (examples of pyrimidine
nucleosides are Cytidine, 2'-Deoxyguanosine, 5-Methyluridine,
2'-Deoxy-5-Methyluridine, Uridine, 2'-Deoxyuridine). The
nucleoside derivatives are involved in important functions in
cellular metabolism and are used to synthesize enzyme
inhibitors, antiviral agents, and anticancer agents. |
