Adenosine, 99%

Product Introduction

Adenosine is a naturally occurring nucleoside composed of the purine base adenine linked to a ribose sugar. It plays a central role in numerous biological processes, including energy transfer, signal transduction, and regulation of cardiovascular and nervous system functions. Due to its versatile biological activity, adenosine is widely used in biochemical research, pharmacology, and molecular biology studies.

Adenosine serves as a key molecule for enzyme assays, receptor studies, metabolic pathway investigations, and drug discovery related to purinergic signaling.

Mechanism of Action

Adenosine can participate in various biochemical and cellular processes:

• Receptor binding: Acts on adenosine receptors (A1, A2A, A2B, A3) to modulate cellular signaling
• Metabolic conversion: Can be phosphorylated to AMP, ADP, and ATP, linking it to cellular energy metabolism
• Enzyme assays: Serves as a substrate or regulator in nucleoside metabolism studies, including adenosine deaminase, adenosine kinase, and other nucleotide-processing enzymes
• Detection is commonly performed via:
  • UV absorbance at 260 nm (typical nucleoside detection)
  • HPLC for quantitative analysis
  • Mass spectrometry for precise identification and quantification
