Guanosine

Guanosine is a nucleoside composed of guanine and ribose. Guanosine is part of nucleotides and nucleic acids.

Guanine is one of four nitrogenous bases that, together with the sugar ribose, form the structure of nucleosides. Ribose binds to guanine through the N9 nitrogen atom. This compound is called guanosine.

Guanosine plays an important role in the construction of RNA and DNA. It is part of such nucleotides as GMP, GDP and GTP. These nucleotides perform various functions in the cell - they are a source of energy, participate in protein synthesis, carry signals, etc.

Thus, guanosine, being a derivative of guanine and ribose, plays a key role in the formation of nucleic acids and the formation of the genetic code of living organisms.



Guanosine (also known as uridine) is a type of monosaccharide found in DNA and RNA, as well as other important molecules. It consists of two components: guanine (base) and ribose (sugar). The formation of a hydrated or non-hydrated guanine derivative depends on the relative concentration of the salt and the type of base reduced or oxidized. At neutral pH, guanine forms two isolated mononucleotide monohydrate bases.

The importance of guanine is due to its important role in DNA and protein synthesis. This is due to the fact that guanine is a component of the nucleic base that makes up the double helix of DNA. In this regard, there is great variability in the amount of guanine in the composition of nucleotide bases in different types of cells. It has been shown that the concentration of guanine changes in response to changes in the level of free bases formed as a result of the catabolism of the macromolecule. It characterizes the level of free nucleic bases in the cell and can affect transcription, replication and DNA repair.

Guanine, in turn, plays an important role in the biological process of DNA replication. Due to its structure, guanine is resistant to ultraviolet light, thus preventing UV-induced inhibition of DNA replication
