摘  要:
谷氨酰胺是血液中含量最丰富的一种游离氨基酸,属于条件性必需氨基酸。谷氨酰胺可维持肠道正常的形态、结构和功能,是肠黏膜细胞重要的能源物质,可促进黏膜的生长、修复及完整性,提高肠道免疫能力,维持肠道微生态稳定,防止细菌移位。文章从谷氨酰胺在肠道中的代谢及其对肠道黏膜的保护作用、对肠道免疫和胃肠道微生态系统的影响等方面对其营养作用进行了综述。

摘  要:
Glutamine(Gln) is one of the most abundant free amino acids in the blood, which is one kind of conditionally essential amino acids. Gln is also an important energy source of intestinal mucosal cells. It can maintain the normal morphology, structure and function of intestine, can promote the growth, repair and integrity of mucosa,and can improve the immunity function of intestine, keep the stability of intestinal microecology and prevent bacterial translocation. This paper summarized the metabolism of Gln in the intestine, protective effect on intestinal mucosa and its important role in the intestinal morphology and intestinal microecology.
