Application

Inosine 5′-monophosphate (IMP) has been used as an umami tastant along with MSG to study their cortical responses and interactions in the human brain. It may be used as a substrate to study the distribution, specificity, and kinetics of inosine-5′-monophosphate dehydrogenase (IMPDH).

Biochem/physiol Actions

Inosine 5′-monophosphate is a purine nucleotide with a flavor-enhancing property. It acts as a precursor for the synthesis of both guanosine monophosphate (GMP) and adenosine monophosphate (AMP).

A novel process for producing inosine 5'-monophosphate (5'-IMP) has been demonstrated. The process consists of two sequential bioreactions; the first is a fermentation of inosine by a mutant of Corynebacterium ammoniagenes, and the second is a unique phosphorylating reaction of

Umami taste perception in mammals is mediated by a heteromeric complex of two G-protein-coupled receptors, T1R1 and T1R3. T1R1/T1R3 exhibits species-dependent differences in ligand specificity; human T1R1/T1R3 specifically responds to L-Glu, whereas mouse T1R1/T1R3 responds more strongly to other L-amino
