最近的研究表明,蛋白质在水合过程中,其吸收水可处于不同的状态。其中一部分水的分子与蛋白质分子表面的亲水部位以氢键相结合,这部分水的分子不参加到冰的点阵中,成为不冻结的水(也称结合水)。而另一部分水,则是可以冻结的水,但由于熔化焓和熔化温度不同,这部分水仍可处于不同的状态。在差示扫描量热法的研究中有关蛋白质中可冻结水与不 Recent studies have shown that the protein in the hydration process, its absorption of water can be in different states. Some of the molecules of water and hydrogen bonds hydrophilic molecules on the surface of the molecule, this part of the water molecules do not participate in the lattice of ice, as non-freezing water (also known as water-binding). While the other part of the water, it can be frozen water, but because of the different enthalpy of fusion and melting temperature, this part of the water can still be in a different state. In the study of differential scanning calorimetry, proteins can be frozen in water and not
