SUMMARY— Nucleotides in rested king crab muscle were identified as NAD, AMP, GMP, IMP, ADP, UDPAG, UDPG, ATP, GTP and UTP. Of three additional minor nucleotide fractions, two are tentatively thought to contain NAD; the third remains unidentified. The nucleotide profiles of three different leg sections were very similar, with ATP the predominant nucleotide. Average total nucleotide content of these three sections was 3.47 μM/g. Muscle from severely exhausted crabs held frozen overnight contained 0.35 μM/g of IMP. Since king crabs are processed fresh and IMP does not accumulate to a very high level, IMP probably does not play an important role in king crab flavor.
