What is L-Threonine

What is L-threonine ?

Threonine was isolated and identified from fibrin hydrolyzate by W.C.Rose in 1935. There are four isomers of threonine, and L-threonine exists naturally and has physiological effects on the body. L-threonine is an essential amino acid. When added to the feed of juvenile piglets and poultry, it is the second limiting amino acid in pig feed and the third limiting amino acid in poultry feed.

Production Processes

L-threonine is produced from cornstarch and other raw materials through liquid submerged fermentation and refining. The flowing chart is as this photo .
