摘要
色氨酸是一种中性、芳香族氨基酸,是5-羟色胺、褪黑素、烟酸等代谢物的前体物质,也是水产动物生长和健康的必需氨基酸。色氨酸除蛋白质合成功能外,还具有调控摄食量、缓解应激反应及提高免疫、抗氧化能力等生理生化功能。本文就色氨酸的代谢途径、水产动物对色氨酸的需要量及色氨酸对摄食、免疫等方面的调控进行综述,以期为色氨酸在水产动物中的研究与应用提供参考。
Tryptophan is a neutral,aromatic amino acid.It is the precursor for the synthesis of the serotonin,melatonin,niacin and other metabolites,and is an essential amino acid for the growth and health of aquatic animals.Tryptophan has physiological and biochemical functions such as regulating feed intake,alleviating stress response,and improving immunity and antioxidant ability,in addition to its participation in protein synthesis.This review covers the metabolic pathways of tryptophan,the requirement of tryptophan in aquatic animals,and the regulation of tryptophan on feed intake and immunity,so as to provide reference for the research and application of tryptophan in aquaculture animals.
