Origin of ribonucleotide:
Any nucleotide having ribose as its sugar
In biochemistry, a ribonucleotide or ribotide is a nucleotide containing D-ribose as its pentose component. It is considered a molecular precursor of nucleic acids. Nucleotides are the basic building blocks of DNA and RNA. The monomer itself from ribonucleotides forms the basic building blocks for RNA. However, the reduction of ribonucleotide, by enzyme ribonucleotide reductase, forms deoxyribonucleotide, which is the essential building blocks for DNA. There are several differences between DNA deoxyribonucleotides and RNA ribonucleotides. Successive nucleotides are linked together via phosphodiester bonds. Ribonucleotides are also utilized in other cellular functions. These special monomers are utilized in both cell regulation and cell signaling as seen in adenosine-monophosphate. Furthermore, ribonucleotides can be converted to adenosine triphosphate, the energy currency in organism. Ribonucleotides can be converted to cyclic adenosine monophosphate to regulate hormones in organisms as well. In living organisms, the most common bases for ribonucleotides are adenine, guanine, cytosine, or uracil. The nitrogenous bases are classified into two parent compounds, purine and pyrimidine.
