1 引言离子通道是镶嵌于细胞膜脂质双分子层的跨膜蛋白 ,容许形状与大小适当的离子从通道蛋白内部的亲水性孔道通过。作顺浓度梯度的跨膜运动 ,从而形成细胞膜离子电流。而细胞膜上所有离子通道电流构成人体生物电的微观世界。自 40年代细胞膜和离子学说建立以来 ,细胞电活动?
1 INTRODUCTION The ion channel is a transmembrane protein embedded in the lipid bilayer of the cell membrane, allowing ions of appropriate shape and size to pass through the hydrophilic channels inside the channel protein. For cis concentration gradient transmembrane movement, thus forming a cell membrane ion current. And all ion channel current in the cell membrane constitutes the micro-world of human bioelectricity. Since the 40’s cell membrane and ion theory was established, the cell’s electrical activity?
