摘　　要：以鲈鱼骨为原料提取得到酸溶性胶原（ASC）和酶溶性胶原（PSC）,对ASC和PSC的性质进行比较。粘度测定结果表明,ASC的变性温度25-30℃,PSC的变性温度为30-35℃;电泳结果表明,ASC和PSC都属于Ⅰ型胶原且纯度比较高;氨基酸分析结果显示,羟脯氨酸和脯氨酸含量ASC均低于PSC,氨基酸检测结果与粘度检测结果相一致。Acid-soluble and pepsin-soluble collagens（ASC and PSC）were extracted from the bond of Lateolabrax japonicus C and partially characterized.The compositions and certain properties of Acid-soluble and pepsin-soluble collagens（ASC and PSC）of the bond of LateolabraxjaponicusC.were strdied.The denaturation temperature（Td）of collagens were researched by viscosity of collagen solution.The Td of ASC and PSC from bone were 25-30 ℃ and 30-35 ℃,respectively.Electrophoretic patterns of collagens from bone were high purity Collagen typeⅠ,hydroxyproline and proline were lower the ASC than the PSC.which was in accordance with the results of composition analysis and Td.
