摘　　要：以梭鱼骨为原料提取得到酸溶性胶原蛋白(ASC)和酶溶性胶原蛋白(PSC),对ASC、PSC的性质进行研究。结果表明:所提取ASC、PSC均属于Ⅰ型胶原,纯度较高;氨基酸组成中甘氨酸含量最高,丙氨酸、脯氨酸、谷氨酸、羟脯氨酸含量相对较高;ASC的变性温度为29.7℃,PSC的变性温度为30.1℃。Acid-soluble collagens(ASC) and pepsin-soluble collagens(PSC) were extracted from the bones of Liza haematocheila and the characteristics of the collagen were studied.The result showed that both of the extracted collagens were of high purity. Amino acid compositions analysis showed that glycine was the most abundant amino acid residue in both collagens,with alanine the second,proline acid the third, glutamic acid the fourth, hydroxyprolinep the fifth. The denaturation temperature of ASC and PSC was 29.7 and 30.1
