有机体赖以正常功能维持生命。正常功能在生命过程中受到各种因素的伤害,因而出现疾病。对有机体的功能与疾病的研究,可以由整体、器官、组织、细胞、亚细胞及大分子不同层次入手。目前,对生物膜的研究活跃在生命学科的各个领域,这是由大分子水平探索生命现象的良好开端。对膜脂、膜蛋白结构的研究,膜流动性概念的提出及膜脂,膜蛋白流动 Organisms rely on their normal function to sustain life. Normal function in the course of life by a variety of factors, thus resulting in disease. The study of the function and disease of the organism can start with the different levels of the whole body, organs, tissues, cells, sub-cells and macromolecules. Currently, research on biofilms is active in all fields of life science, which is a good start to exploring life phenomena at the macromolecular level. The membrane lipid, membrane protein structure, the concept of membrane fluidity and membrane lipid, membrane protein flow
