支链氨基酸(BCAA)及水产动物对其需求量的研究进展

Research progress of branch chain amino acids(BCAA) and its requirement for aquatic animals

支链氨基酸(Branch chain amino acid,BCAA)作为动物的必需氨基酸,在水产动物中具有重要的生理功能。文章介绍了各支链氨基酸的生理功能及各支链氨基酸的代谢关系,综述了水产动物对支链氨基酸(亮氨酸、异亮氨酸、缬氨酸)的需求量,以期为更进一步的研究支链氨基酸的相互关系及其在水产动物中的代谢提供参考。

As essential amino acids,branch chain amino acids（BCAA） play an important physiologicalfunction for aquatic animals.This research introduced the physiological function of branch chain ami-no acids as well as the metabolism relationship,reviewed the quantity requirement of branch chainamino acids（leucine,isoleucine,valine） for aquatic animals,in order to provide a reference for furtherstudy in branch chain amino acids about the interrelation and the metabolism in aquatic animals.
