Nucléosides et Nucléotides
Les nucléosides sont des composés formés par une base azotée liée à un sucre (ribose ou désoxyribose). Lorsqu’un groupe phosphate est ajouté au nucléoside, un nucléotide est formé. Ces composés sont essentiels en biologie cellulaire, car les nucléotides sont les blocs fondamentaux de l’ADN et de l’ARN, responsables du stockage et de la transmission de l’information génétique. Les nucléosides ont des applications dans le traitement des maladies virales, en tant qu’inhibiteurs de la réplication virale. Les nucléotides, en plus de leur rôle structurel dans les acides nucléiques, interviennent dans les processus énergétiques, comme la synthèse de l’ATP.
Chez CymitQuimica, nous proposons une large gamme de nucléosides et de nucléotides essentiels à la recherche en biologie moléculaire, virologie et pharmacologie.
