What is IMP?

Chemical properties

White solid

The Uses of IMP

Inosine 5''-monophosphate from Saccharomyces cerevisiae is an IMPDH substrate.

The Uses of IMP

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).

What are the applications of Application

Inosine 5′-monophosphate is an IMPDH substrate

Definition

ChEBI: IMP is a purine ribonucleoside 5'-monophosphate having hypoxanthine as the nucleobase. It has a role as a human metabolite, an Escherichia coli metabolite and a mouse metabolite. It is a purine ribonucleoside 5'-monophosphate and an inosine phosphate. It is a conjugate acid of an IMP(2-).

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).
