Adenosine is a nucleoside comprised of adenine attached to a ribose (ribofuranose) moiety via a -N9-glycosidic bond. Deoxyadenosine monophosphate is a derivative of the common nucleic acid ATP or adenosine triphosphate in which the -OH (hydroxyl) group on the 2' carbon on the nucleotide's pentose has been removed (hence the deoxy- part of the name).
