The Effect of Type I Antifreeze Proteins on The Equilibrium Structure of Interfacial Layer of Ice Crystal
第一类鱼抗冻蛋白对冰晶生长界面层结构的影响

Based on the thermodynamic properties of ice crystal in aqueous solution and using multilayer model, Gibbs functions of interfacial layer of ice crystal in pure water and antifreeze protein solution were obtained respectively. Equilibrium structures of interfacial layer of ice crystal in three kinds of type I antifreeze protein solution were analyzed by using the Gibbs function. Equilibrium structures of interfacial layer of ice crystal in pure water and antifreeze protein solution were different. The effect on the shape of ice crystal that caused by change of equilibrium structure of interfacial layer of ice crystal was discussed. It is a theoretical evidence for understanding the experiment results that the growth habits and shape of ice crystals are different in antifreeze protein solution and pure water.
