Nucleosides and Nucleotides
Nucleosides are compounds formed by a nitrogenous base linked to a sugar (ribose or deoxyribose). When a phosphate group is added to the nucleoside, a nucleotide is formed. These compounds are essential in cellular biology, as nucleotides are the fundamental building blocks of DNA and RNA, responsible for storing and transmitting genetic information. Nucleosides have applications in the treatment of viral diseases, acting as inhibitors of viral replication. Nucleotides, besides their structural role in nucleic acids, are involved in energy processes, such as ATP synthesis.
At CymitQuimica, we offer a wide range of nucleosides and nucleotides essential for research in molecular biology, virology, and pharmacology.
