Abstract
L-tryptophan is one of the essential amino acids for the human or animal,which is the precus of 5-hydroxytryptamine,N-acetyl-5-methoxytryptamine,L-Kynurenine,nicotinic acid and so on.L-tryptophan has two metabolic pathways:the one is kynurenine pathway,the other is 5-hydroxytryptamine pathway.Although the level of tryptophan in human and animal is less,it and its metabolites play the vital role not only on regulating protein synthesis,but also on controlling animal appetite,adjusting the immune response,and improving mood and cognitive function.In recent years,the application of tryptophan and its metabolites is becoming more and more widely.L-tryptophan has been widely applied in food,feedstuff,medicine and other fields.In this paper,the effects of L-tryptophan and its metabolite 5-hydroxytryptamine on animal intestinal immune,intestinal peristalsis and irritable bowel syndrome were summarized.
