Description

Application

Inosine 5′-monophosphate (IMP) is used as a substrate to study the distribution, specificity and kinetics of inosine-5′-monophosphate dehydrogenase (IMPDH).

Inosine 5′-monophosphate disodium salt hydrate has been used:

• as a 5′-ribonucleotide tastant compound in taste-detection threshold tests in chicks
• for standard curve generation in high-performance liquid chromatography (HPLC) to quantify IMP from prawn tail tissue samples
• as a component of McCoy′s 5A complete medium for Plasmodium vivax culture

Biochem/physiol Actions

Inosine 5′-monophosphate (IMP) is a dietary nucleotide that is synthesized from adenosine monophosphate (AMP) in eukaryotes. It is a food additive and is essential for intestinal health and immunity.

Inosine monophosphate, or inosinic acid, is the ribonucleotide of hypoxanthine and the first nucleotide formed during purine synthesis.
