Description
Remarque sur l'analyse
Nucleosides are structural subunits of nucleic acids, the macromolecules that convey genetic information in living cells. They contain a molecule of sugar (pentose) bonded to a nitrogen-containing organic ring compound. The nitrogen-containing compound is either a pyrimidine (cytosine, thymine, or uracil) or a purine (adenine or guanine). Nucleosides, derivatives and / or analogues can be used in many different industries and applications as in agrochemistry (herbicides, fungicides and insecticides), therapeutic drugs including a range of antiviral (HIV, hepatitis C virus and herpes simplex) and even antibiotics.
