GENERAL DESCRIPTION & APPLICATIONS |
||
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 deoxyribose, 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.
Thymine is a pyrimidine base, occurring condensed with deoxyribose to form the nucleoside deoxythymidine in animal cells. Thymidine is significant because of its involvement in the biosynthesis of DNA and in the preservation and transfer of genetic information. It was thought that there is no thymine in ribonucleic acid (RNA); the thymine nucleotides contain only deoxyribose. However, It is now known that thymine, produced from uracil by post-transcriptional methylation, occurs as a rare base in rRNAs and tRNAs. When N1 is linked to the C1 of ribose, thymine forms a pyrimidine nucleoside called thymidines which are phosphorylated with from one to three phosphoric acid groups to form the three nucleotides; thymidine monophosphate(TMP), thymidine diphosphate(TDP), and thymidine triphosphate (TTP) respectively. TTP is involved in the formation of adenosine triphosphate (ATP) as a donator of phosphate groups to adenosine diphosphate (ADP).
Chemically modified nucleotides substituted or attached by special chemical groups or elements are studied and used to inactivate the normal biological operation in the living organism and the function of important enzymes. |
