摘　　要：生物膜结构在细胞生理过程中发挥了重要作用,是目前生命科学研究的前沿领域之一。但在本科生物化学课程教学中,生物膜相关内容较少,特别是关于生物膜不对称性的特点是教学中的薄弱环节。本文以生物膜"流动镶嵌"模型为要点,联系膜脂分子的结构、形状与功能,介绍一种利于同学理解和记忆膜脂分子在双分子层不对称分布的方法。该方法有助于提高教学效果和学生的学习兴趣。The biological membranes play important roles in cell physiology. The study of biological membranes is one of the frontiers in life sciences at present. However, the chapter of biological membranes in the teaching process of Biochemistry is too brief, especially for the significance of asymmetric property of biological membranes. Here we focus on the “fluid and mosaic model” of biological membranes and introduce a new method about teaching and learning the asymmetrical distribution of membrane lipids, based on the internal association of molecular structure, shape and functions. This method is helpful to improve the teaching effect and students’ interest in learning.
