半胱氨酸的生物代谢及其在动物生产中的应用研究进展OACSTPCD

Cysteine is a semi-essential sulfur-containing amino acid,which plays an important role in regulating nutrient absorption,immune function,intestinal repair and alleviating oxidative stress.Its metabolic pathway involves a variety of enzymes and products.At present,the research on cysteine in animal nutrition and cellular immunology has greatly improved the possibility of its application in agricultural production practice.In this paper,the sources,metabolic pathways,metabolites of cysteine in vivo and the research progress of cysteine in animal production were reviewed,and the roles of cysteine in animal production,immune metabolism and antioxidant were discussed,so as to provide a reference for the research and application of cysteine in animal feed.
