Nucleosides are glycosylamines made by attaching a nucleobase to a ribose ring. Examples of these include cytidine, uridine, adenosine, guanosine, thymidine and inosine.

Nucleosides can be phosphorylated by specific kinases in the cell, producing nucleotides, which are the molecular building blocks of DNA and RNA.

Nucleoside triphosphates are the energy rich end products of the majority of biochemical energy releasing pathways.
