Abstract: The properties of two types of pepsin-soluble collagens(PSC) from the skin and bone of carp(Cyprinus carpio) were studied. The Tds(denaturation temperatures) of PSC from carp skin and bone are 28.1 ℃ and 30.0 ℃ respectively by the method of viscosity measurement. Electrophoretic patterns of PSC from carp skin and bone are very similar,while the pattern of bone PSC shows more cross-linking components. The results of differential scanning calorimetry(DSC) indicated that PSC from carp bone has higher Tmax(maximum transtion temperature) than PSC from carp skin,which is in accordance with the results of composition analysis.
