为维持生命而进行的水的输送是生命必须活动。长期以来普遍认为,细胞内外的水分子是以简单的跨膜扩散方式透过脂质双分子层。近年来,在许多动、植物及微生物中相继发现类似的专一性运输水的通道,统称为水通道蛋白(aquaporin,AQP)。 The delivery of water to sustain life is vital to life. It has long been widely accepted that water molecules inside and outside cells penetrate the lipid bilayer in a simple, transmembrane manner. In recent years, many animals, plants and microorganisms have been found similar to the transport of water-specific channels, collectively referred to as aquaporin (aquaporin, AQP).
