We also got STM images of denatured fibroin under stress or by methanolin molecular level. We found the conformation of silk fibroin is changed from α-helixand random coil structures to β-strand and loosed α-helix formation. We employed the STM to explore the structure and morphology of silk fibroinin the middle silk gland of mature silkworm.

我们在分子水平上对在冰冻和甲醇处理下的丝心蛋白的变性情况进行了STM研究，我们发现丝心蛋白的构象由α-螺旋结构和无规线团的结构向β-伸展链和松散折叠α-螺旋结构转变我们还用STM对熟蚕的中部丝腺体中的丝心蛋白的结构形态进行了研究。
