Sodium 4-amino-1-((2R,3R,4S,5R)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-2-oxo-1,2-dihydropyrimidin-5-yl hydrogendiphosphate, is commonly known as adenosine diphosphate (ADP). It is a crucial molecule involved in various cellular processes, including energy transfer, enzyme co-factor activity, and signal transduction. ADP is integral to cellular respiration and ATP synthesis. It has wide-ranging applications in biological research, diagnostics, pharmaceutical development, and biochemical studies due to its importance in cellular biochemistry, energy metabolism, and drug development. Additionally, ADP is a significant target for drug development, particularly in the context of cardiovascular diseases and thrombosis, as ADP receptor antagonists are used as antiplatelet drugs.
