【摘要】 丝素溶液在一定条件下发生凝胶， 丝素结构从液态时的无规卷曲转化为凝胶状态时的β构象， 其干胶粉末也为β构象。丝素凝胶具有较高的结晶性， 其结晶部分是由Ｇｌｙ， Ａｌａ，Ｓｅｒ， Ｔｙｒ 等氨基酸组成， 为一稳定的蛋白质凝胶。更多还原

【Abstract】 The gelation of fibroin solution occurs on certain conditions.The structure of fibroin is changed from random coil to β structure during gelatinizing.And the structure of dried gel powder is also the β structure.The fibroin gel has high degree of crystallinity.And the crystalline region of the fibroin consists of Gly,Ala,Ser,and Tyr etc.更多还原
