鱼类精氨酸营养生理研究进展

精氨酸为鱼类的必需氨基酸之一，其在鱼体内参与蛋白质、多胺的合成，促进生长；精氨酸具有促内分泌作用；精氨酸可在体内生成一氧化氮，一氧化氮参与鱼类心血管活动、免疫功能的调节。某些鱼类可能具有自身精氨酸的合成能力。鱼类赖氨酸一精氨酸拮抗存在种问差异。本研究从精氨酸的合成、生理功能、与赖氨酸的关系以及需求量等方面对鱼类精氨酸的营养生理研究进行了综述。[中国水产科学，2006，13（4）：679-685]

The recent advance on arginine nutritional physiology in fish

Arginine is one of the essential amino acids for fish.It has fundamental roles in protein synthesis,polyamine synthesis and stimulates hormone release.Arginine is the major substrate for production of nitric oxide,which plays an important role in regulation of cardiovascular system and immune function.In some fish species,arginine can be synthesized in vivo.In this paper,we reviewed the recent advance of arginine on main metabolism path,physiological function,requirement and relationship with lysine in fish.
