  4. The md simulation data were analyzed in terms of average atomic positions, root mean square ( rms ) fluctuations, monomer - monomer interactions, hydrogen bond ( h - bond ) network, secondary structure, and so on. through the comparison, we found that when the system includes zn2 + ions and phenol, the stability of insulin hexamer is enhanced, but the conformational flexibility related to its biological activity is decreased. in addition, the insulin hexamer tends to dissociate in the absence of zn2 + and phenol

    通過對這兩個模擬所得到的軌跡在原子的平均位置、方均根漲落、方均根偏差、單體之間相互作用、氫鍵網路、二級結構等方面進行的比較分析發現，對于包含鋅離子和苯酚的體系，胰島素六聚體的穩定性得到了增強，但其構象柔性卻受到了削弱；對不含鋅離子和苯酚的體系，胰島素六聚體的穩定性明顯減弱，構象柔性卻表現得較為突出，在這種情況下，胰島素六聚體還表現出解聚的傾向。
  5.
