Abstract

The sensitivity of several fish myofibrils (tilapia, carp, rainbow trout, and walleye pollack) to peroxidized triglyceride (P-TG) was compared in terms of K-ATPase decrease and myosinheavy chain crosslinking.<br> Upon incubation of myofibrils with P-TG, myofibrillar K-ATPase activity decreasedand myosin heavy chain cross-linking took place for all species of fish. These two changes proceeded according to the two-step first-order reactions; a quick early change was followed by a slow change. Both in the early and the later phase of the K-ATPase decrease and the myosin heavy chain cross-linking, the rate constant estimated for walleye pollack myofibrils was the greatest among the four fish species and was followed in descending rate order by rainbow trout, carp, and tilapia.<br> The order was in good accordance with that of the thermostability of respective myofibrils. Therefore, it was suggested that species-specific reactivity of myofibrils to P-TG was related to the structural stability of whole mvosin molecule.
