【摘要】以鲤鱼鱼皮和鱼骨为原料提取得到酶溶性胶原蛋白(PSC),对鱼皮PSC和鱼骨PSC的性质进行比较。电泳结果表明,鱼皮PSC和鱼骨PSC都属于Ⅰ型胶原;2种胶原蛋白中,脯氨酸和羟脯氨酸含量均低于牛皮酸溶性胶原蛋白;粘度测定的结果显示,鱼皮PSC的变性温度为28.1℃,鱼骨PSC的变性温度为30.0℃;差热分析的结果说明,鱼骨PSC的热稳定性高于鱼皮PSC,这与氨基酸分析和粘度分析的结果相一致;傅立叶红外光谱分析结果显示,鱼皮PSC和鱼骨PSC结构具有很大的相似性。更多还原

【Abstract】 The compositions and certain properties of pepsin-soluble collagens（PSC）of the skin and bone of carp（Cyprinus Ca rpio）were studied.The denaturation temperature（T_d）of collagens were researched by viscosity of collagen solution.The T_d of PSC from carp skin and bone were 28.1℃and 30.0℃,respectively. Electrophoretic patterns of collagens from skin and bone were very similar,while the pattern of bone collagen showed more cross-linking components.The results of differential scanning calorimetry（DSC）indicated PSC from bone had higher maximum transition temperature(T_max)than PSC from skin,which was in accordance with the results of composition analysis and Td.FTIR spectra showed the structures of the collagens were similar.更多还原
