谷氨酰胺(glutamine,Gln)是血液循环和组织内游离氨基酸池中含量最丰富的一种氨基酸,既能为氨基酸、蛋白质、核酸的合成提供氮源,又能被氧化释放能量。Gln是一种特殊的营养物质,是一种条件性必需氨基酸,约占全身游离氨基酸的60%,它是血浆中含量最高的氨基酸,正常血浆浓度为0.6~0.9 mmol/L。近年来,随着临床营养领域研究的不断深入,单纯的营养支持已逐步转为免疫营养治疗的概念。Gln能够提
Glutamine (glutamine, Gln) is one of the most abundant amino acids in blood circulation and free amino acid pools in tissue, which not only provides nitrogen source for the synthesis of amino acids, proteins and nucleic acids, but also oxidizes to release energy. Gln is a special nutrient that is a conditionally essential amino acid, accounting for about 60% of free amino acids in the body. It is the most abundant amino acid in plasma with a normal plasma concentration of 0.6-0.9 mmol / L. In recent years, with the continuous deepening of the research in the field of clinical nutrition, simple nutritional support has gradually shifted to the concept of immune nutrition therapy. Gln can mention
