Inosine 5'-monophosphate disodium salt (IMP·Na₂) is a naturally occurring purine nucleotide that plays an important role in nucleotide metabolism and cellular energy pathways. It is an intermediate in the biosynthesis and degradation of purine nucleotides, linking the metabolic pathways of adenosine and guanosine nucleotides.
IMP functions as a key branch point in purine metabolism, where it can be converted into adenosine monophosphate (AMP) or guanosine monophosphate (GMP) through enzymatic reactions. Because of its central role in nucleotide biosynthesis, IMP is widely used in biochemical studies of purine metabolism, enzyme assays, and molecular biology research.
Due to its biological relevance, inosine 5'-monophosphate disodium salt is commonly applied in enzymology, metabolic pathway research, and biochemical studies involving nucleotide-processing enzymes.
