摘　　要：蛋氨酸作为水产动物正常生长、代谢的必需氨酸,是低鱼粉饲料的主要限制性氨基酸,在合成蛋白质、提供甲基、生成半胱氨酸中发挥重要作用。蛋氨酸也是机体内多胺、肌酸、磷脂酰胆碱、谷胱甘肽、牛磺酸及辅酶A等生物合成的前体物质。本文综述了蛋氨酸的代谢途径、水产动物蛋氨酸的需求量、蛋氨酸与其他营养素的相互作用及其对水产动物健康的影响,以期为蛋氨酸在水产动物中开展深入研究提供参考。Methionine,as an essential amino acid for normal growth and metabolism of aquatic animals,is the main limiting amino acid in low-fish meal diet,and plays an important role in protein synthesis,methyl supply and cysteine production. Methionine is also the precursor of biosynthesis of polyamine,creatine,phosphatidylcholine,glutathione,taurine and coenzyme A. This review summarized methionine metabolism pathway,the methionine requirement of aquatic animals,the interaction between methionine and other nutrients,and the effects of methionine on the health of aquatic animals,in order to provide references for further research on methionine in aquatic animals.
