摘要

谷氨酸作为幼年动物重要的氨基酸,是肠内能量生成的最大贡献者,它不能由机体自身合成,需额外添加或通过谷氨酸前体物谷氨酰胺转化而成。谷氨酸是谷胱甘肽合成的重要底物,对动物肠道抗氧化剂的提供有重要作用,其转运依靠谷氨酸转运载体完成。因此,本文就谷氨酸和谷氨酰胺转运系统的分类及作用机制做一综述。

Abstract

Glutamate is the largest contributor to intestinal energy generation as an essential amino acid for young animal growth, and it is obtained from diets or transformed from glutamine because it cannot be synthesized in vivo. Glutamate is an important substrate for glutathione synthesis and plays a critical role in supplying intestinal antioxidants, and its transporters are responsible for removing glutamate from the extracellular space. Functions and characteristics of glutamate and glutamine transport systems are reviewed in this article.[Chinese Journal of Animal Nutrition, 2011, 23(6):901 -907]
