Nucleotide composition
Belonging to the family of nucleosides, the nucleotide is the base of the nucleic acid, that is to say, DNA and RNA, which are present in each of the cells of the human body. It consists of one to three phosphates (derivatives of phosphoric acid), a sugar called "ose" with five carbons, or "pentose", and a nitrogenous base. If the first two elements are always identical from one nucleotide to another, the nitrogen base, for its part, varies.
Forms of nucleotides
The nucleotides present in DNA, called "deoxynucleotides", come in four distinct forms, the nitrogen base of which is different for each of them. Deoxyadenosine, deoxythymidine, deoxyguanosine and deoxycytidine are distinguished.
The same goes for those of RNA, called "ribonucleotides", for which there is differentiation between adenosine, uridine uridine, guanosine and cytidine.
Nucleotide functions
If the nucleotides, by joining together like a chain, form the DNA and thus the genetic identity, they also have other roles of which that of bringing energy. In addition, they are used in some medicines. Finally, studies have highlighted that they would be a stimulant for the development of the immune system.
