固定化酶是将水溶性的酶用物理或化学方法处理,使之变成不溶于水的仍具有酶活性的酶衍生物。在催化反应中,它以固相状态作用于底物。固定化酶不但仍然具有酶的高度专一性及温和条件下高效率催化的特点,还可反复使用。这样,酶经固定后,稳定性有较大增加,可贮藏较长时间。 用高分子复合物固定生物酶是固定化酶的一个新的尝试。两种不同的高分子链通过氢键力、库伦力、范德华力、疏水键力等所谓次价键而聚集成高分子复合物。高分子复合物具有一些特殊功能,如优良的质量传递性能、对水、电解质的灵敏介电特性,对氧和水 Immobilized enzymes are water-soluble enzymes that are physically or chemically treated to render them into water-insoluble, enzymatically-active enzyme derivatives. In the catalytic reaction, it acts on the substrate as a solid phase. Not only does the immobilized enzyme still have the high specificity of the enzyme and the high efficiency of catalysis under mild conditions, it can be used repeatedly. In this way, the enzyme is fixed, a greater increase in stability, can be stored for a long time. Immobilization of biological enzymes with polymer complexes is a new attempt to immobilize enzymes. Two different polymer chains are aggregated into polymer complexes by so-called subvalent bonds such as hydrogen bond force, coulomb force, van der Waals force, hydrophobic bond force and the like. Polymer complexes have some special features such as excellent mass transfer properties, sensitive dielectric properties for water and electrolytes, oxygen and water
