'''流动镶嵌模型''' ；<ref>[[David L. Nelson & Michael M. Cox.Lehninger Principles of Biochemistry SEVENTH EDITION.:W. H. Freeman and Company,2017.]]</ref>  ：是膜结构的一种假说模型。脂类物质分子的双层，形成了膜的基本结构的基本支架，而膜的蛋白质则和脂类层的内外表面结合，或者嵌入脂类层，或者贯穿脂类层而部分地露在膜的内外表面。[[磷脂]]和蛋白质都有一定的流动性，使膜结构处于不断变动的状态。

流动镶嵌模型模型认为：细胞膜结构是由[[液态]]的脂类双分子层中镶嵌可以移动的球形蛋白质而形成的。随着科学研究技术的不断创新和改进，流动镶嵌模型也逐步得到完善，是公认的膜结构模型的基础。

这一模型有两个结构特点：一是膜的流动性，膜蛋白和膜脂均可侧向移动；二是膜蛋白分布的不对称性，蛋白质有的镶嵌在膜的内或外表面，有的嵌入或横跨[[磷脂双分子层]]。

有一个功能特点：选择透过性。
