Abstract
Thermal properties of several jellyfish mesogloea were studied using the differential scanning calorimeter. As a result, the three endothermic peaks were shown for many jellyfish. The first, second, and third peak corresponded to myosin, sarcoplasmic proteins and/or collagen, and actin. Each transition temperature (Tm) in jellyfish were lower than those in mammals. Although the three endothermic peaks were shown for hydrozoan jellyfish, the highest Tm were lower than the lowest one for the other jellyfish. Only two peaks were shown for cubic jellyfish. It was suggested that the first and second peak corresponded to sarcoplasmic protein and/or collagen and actin.
Moreover, it did not related between the water temperature in the sampling occasion and the denaturation temperature of each protein in jellyfish.
