Adenosine

[ Description ]
Adenosine is a purine nucleoside composed of adenine attached to a ribose sugar. It is a fundamental building block of RNA and plays important roles in energy transfer, biochemical signaling, and medical applications.

[ Source and Characteristics ]
[ source: ] Naturally present in all living cells as a purine nucleoside.
[ appearance: ] White crystalline powder.
[ CAS: ] 58-61-7
[ Molecular Formula: ] C₁₀H₁₃N₅O₄

[ Main Components ]
Adenosine consists of two primary components: adenine (a purine base) and ribose (a five-carbon sugar) linked through a β-N₉-glycosidic bond.

[ Applications ]
1. Essential nucleoside in RNA synthesis.
2. Precursor of energy molecules such as AMP, ADP, and ATP.
3. Involved in signal transduction through cyclic AMP (cAMP).
4. Used as a clinical medication to treat supraventricular tachycardia.
5. Applied in diagnostic imaging of myocardial perfusion.
6. Functions as a physiological modulator in vasodilation and anti-inflammatory processes.
