Inosine monophosphate (imp, disodium inosinate)

Flavor enhancer: Soups, sauces, seasonings.
IMP and guanosine monophosphate (GMP) are used together to enhance the meaty (umami) flavor of soups and other foods. They are often used together with monosodium glutamate (MSG), because they enhance its potency. These safe 5'-ribonucleotides are produced together.
