| 摘 要： | 利用醋酸及胃蛋白酶从鮰鱼鱼皮中提取了胶原,并对其物理与化学特性进行了探讨研究。结果表明:提取的胶原属于典型的Ⅰ型胶原,胶原的三股螺旋分子组成为α1(Ⅰ)]2α2(Ⅰ)。氨基酸组成及变性温度的分析说明提取的鮰鱼皮胶原由于其自身亚氨基酸含量的特征,使得它的稳定性远远高于其他鱼类的皮胶原,但仍然比大多数哺乳类动物皮胶原稳定性要弱。紫外扫描光谱、傅立叶红外光谱及圆二色性研究结果证明提取的胶原三股螺旋结构保持完整。

| Abstract: | Acid-soluble collagen(ASC) and pepsin-soluble collagen(PSC) were obtained from channel catfish skin and partially characterized.The collagen from the skin of channel catfish had special amino acid composition,which make it much more stable than any other fish skin collagen.SDS-PAGE,CD,UV-Vis and FTIR spectra of channel catfish skin collagen were carried out and the results suggested that ASC and PSC were typical typeⅠcollagen with integrality of triple-helix. |
