Nucleotides

Nucleotides are organic compounds that consist of three joined structures: a nitrogenous base, a sugar, and a phosphate group. The most common nucleotides can be divided into two groups (purines and pyrimidines) based on the structure of the nitrogenous base. The joined sugar is either ribose or deoxyribose.

Nucleotide Synthesis And Structure

A nucleotide is composed of a ring of nitrogen, carbon and oxygen atoms, a five carbon sugar (together referred to as a nucleoside) and one phosphate group. Nucleotides can be synthesized through a variety of methods both in vitro and in vivo. This can involve salvage synthesis (the re-use of parts of nucleotides in resynthesizing new nucleotides through breakdown and synthesis reactions in order to exchange useful parts), or the use of protecting groups in a laboratory.

This can involve salvage synthesis (the re-use of parts of nucleotides in resynthesizing new nucleotides through breakdown and synthesis reactions in order to exchange useful parts), or the use of protecting groups in a laboratory. In the latter case, a purified nucleoside or nucleobase is protected to create a phosphoramidite, and can be used to obtain analogues not present in nature and/or to create an oligonucleotide.
