Hypoxanthine was the major catabolite of adenosine triphosphate (ATP) in rock, yellowfin, flathead and Dover soles examined from the Gulf of Alaska. Inosine monophosphate (IMP)/hypoxanthine (Hx) ratios were as effective as K1 values for assessing freshness. In contrast, inosine (HxR) was the end catabolite in rex sole and hypoxanthine was barely detectable. The gradual accumulation of hypoxanthine in rock and yellowfin soles made this catabolite a useful freshness indicator for these species.
