氨基酸的生物活性及其营养调控功能的研究进展

摘要

随着氨基酸营养研究的深入,发现部分氨基酸及其代谢产物在体内具有的生物活性对营养物质代谢、神经内分泌调节、基因表达、信号转导及免疫功能等都具有调控作用,这些氨基酸包括精氨酸、谷氨酰胺、亮氨酸、色氨酸、苏氨酸等,本文综述了这些氨基酸在动物体内的代谢途径以及它们的营养调控功能的研究进展.%With the continuous research on amino acid nutrition, it was found that biological activities of certain amino acids and their metabolites in animal body had regulation functions on nutrient metabolism, neuroen-docrine modulation, gene expression, signal transduction, immunity, etc. These amino acids include arginine, glutamine, leucine, tryptophan, threonine, etc. The metabolic pathways and functions of nutritional regulation of these amino acids were reviewed in this paper.
