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).
