INOSINE MONOPHOSPHATE (IMP) AND HYPOXANTHINE FORMATION IN THREE SPECIES OF SHRIMP HELD ON ICE

The major pathway for degradation of adenine nucleotides in pink (Pandalus borealis), spot (Pandalus platyceros), and sidestripe (Pandalopsis dispar) shrimp results in formation of inosine monophosphate (IMP) and hypoxanthine. The IMP content of shrimp held on ice increased to 2–3 μM/g during the first day and decreased to 0.4–0.7 μM/g during the next two weeks, while 0.8–1.3 μM/g of hypoxanthine accumulated during this period.
