抗冻蛋白活性的吸附动力学模型

A Model on the Adsorption Kinetics of Antifreeze Protein Activity

根据抗冻蛋白溶液中抗冻蛋白分子与冰晶表面相互作用特点,提出抗冻蛋白与冰晶表面相互作用模型.进而,利用饱和分数与抗冻活性之间的关系,给出抗冻活性与抗冻蛋白浓度的理论关系.根据此关系做出了与实验数据符合较好的抗冻活性与抗冻蛋白浓度关系的理论曲线.另外,对抗冻蛋白分子与冰晶表面相互作用的特点作了进一步的讨论.

According to the properties of the interaction between the molecules of antifreeze protein and the ice crystal surface in the solution of antifreeze protein,a model on the interaction between the molecules of antifreeze protein and the ice crystal surface is proposed. The theoretical relations between the antifreeze activity and concentration of antifreeze protein are given by using of the relation between the saturation fraction and antifreeze activity.The theoretical curves of relations between the antifreeze activity and consentration of antifreeze proteins are given by using of these relations.These theoretical results are consistent with experimental datum.Furthermore,the properties of interaction between the molecules of antifreeze protein and the ice crystal surface are discussed.
