有一个搅动的透明小容器的一个光生物传感器被用来带着二只水溶性的猫监视使不能调动的小麦细菌凝集素(WGA ) 的相互作用免费基础卟啉和它的 Zn (II ) 的离子的 por-phyrins.The 协会常数(K_a ) 复杂形式 2。第 66a 27.31 x 10 ~ 在 20 C 的 5 L/mol 分别地。免费基础卟啉的相互作用进一步在在 15 C 和 37 C 之间的温度被调查。热力学参数,在免费精力的变化,热含量和熵,—31.23, 22.92, 54.15 kJ/mol 分别地。热能力变化是—355.53 J 中心点 mol~(-1) 中心点 K~(-1) 。绑定是驾驶 byentropic 贡献,并且显示出强壮的热含量熵赔偿。它首先被恐水病的力量管理。
An optical biosensor with a stirred cuvette has been used to monitor the interaction of immobilized wheat germ agglutinin (WGA) with two water-soluble cationic porphyrins, The association constants (Ka) of the free base porphyrin and its Zn(Ⅱ) complex form were 2. 66 and 27.31 × 10^5 l,/mol at 20 ℃ respectively. The interactions of the free base porphyrin were further investigated at temperatures between 15 ℃ and 37 ℃, The thermodynamics parameters, changes in free energy, enthalpy and entropy, were -31.23, 22.92, 54.15 ld/mol respectively. The heat capacity change was -355.53 J · mol^-1·K^-1 The binding was driven by entropic contribution, and showed strong enthalpy-entropy compensation. It was governed primarily by hydrophobic forces.
