摘　　要：磷对动物来说具有重要的生理功能。它主要以无机磷的形式在小肠和肾脏近端小管上皮细胞的刷状缘膜被吸收和重吸收,它的吸收转运过程是一个借助于钠磷协同转运蛋白与钠离子一起的主动转运过程,并且磷的吸收受很多因素的调节。在充分了解磷的吸收转运机制以后既可以保证动物以最佳状态生长,又可以使由于磷造成的环境污染降到最低。本文就磷的吸收转运机制最新研究进展进行了概述。Phosphorus has essential physiological function to animals. It was absorbed on apical membrane of small intestinal epithelial cells and reabsorbed on renal brush border membrane. The active uptake and transport of phosphorus are coupled to Na^＋ uptake by the Na^＋/phosphate cotransporter, and the progress of active uptake and transport was regulated by many factors. We could reduce environmental pollution which caused by phosphorus significantly, and make sure animals growing best after knowing the mechanism of absorption and transport of phosphorus. This article summerized the update progress in the mechanism of absorption and transport of phosphorus.
