ADP (Adenosine 5' diphosphate) disodium salt dihydrate is a nucleotide used in a wide range of biochemical research applications. ADP plays a critical role in energy metabolism as a key intermediate in ATP generation and cellular energy transfer. It is commonly used in enzyme assays to study phosphorylation, ATP hydrolysis, and signal transduction pathways. The 1g quantity is ideal for laboratories conducting experiments related to cellular energy production, G-protein signaling, and other nucleotide-based biochemical reactions. ADP is also a valuable reagent in research on enzyme kinetics and metabolic disorders, where the modulation of ATP and ADP levels is a key focus.
