Adenosine is an endogenous nucleoside found throughout human cells

A term in cell biology that refers to a compound formed by connecting N-9 of adenine and C-1 of D-ribose through a β-glycosidic bond, and its phosphate ester is adenylate.

Adenosine is an endogenous nucleoside found throughout human cells. It can directly enter the myocardium and be phosphorylated to generate adenosine, which participates in myocardial energy metabolism. It also participates in the expansion of coronary blood vessels and increases blood flow. Adenosine has physiological effects on the cardiovascular system and many other systems and tissues of the body. Adenosine is an important intermediate used in the synthesis of adenosine triphosphate (ATP), adenine, adenylate, and vidarabine.
