Adenosine is a nucleoside in which the base adenine is covalently linked to the 1′-carbon of the sugar ribose. In the adenosine phosphates, there are one, two, or three phosphate groups also bonded to the ribose, typically linked in series to the 5′-carbon of the sugar. The bond connecting the first phosphate group to the carbon is a phosphoester bond, and the bonds between the phosphate groups are phosphodiester bonds. The adenosine phosphates include adenosine

5′-triphosphate (ATP), adenosine 5′-diphosphate (ADP), and adenosine 5′-monophosphate (AMP). Nucleosides to which phosphates are attached are also referred to as nucleotides.
