[Chemical name]9- β-D-Ribofuranosyl adenine
[Molecular formula]C₁₀H₁₃N₅O₄
[Molecular weight]267.24

[Use]It is a inner-borning nucleoside can be found all over the  human  body, can directly enter cardiac muscles and be phosphated  to adenosine  phosphate, take part in energy metabolism of cardiac  muscles, moreover alsotake part in expanding of cardiac blood vessels, enlarge blood flow. Adenosine have physiological actions to cardiac blood vessel system, many other systems and tissues. It is an important intermediate in synthesis of ATP, adenine,  adenosine  phosphate and vidarabine. [Specifications]
