Degradation of Inosine 5′-Monophosphate in the Skeletal Muscle of Several North Atlantic Fishes
The rates of breakdown of inosine 5′-monophosphate (IMP) and of its product, inosine (Ino), varied considerably in the muscles of Atlantic cod, haddock, pollock, Atlantic halibut, American plaice, and winter flounder when stored in ice. Haddock and Atlantic halibut were noteworthy in having a very s...
