Uses 1.Threonine is a feed nutrient enhancer, being the essential amino acids for the growth of livestock and poultry fish. It is mainly added to wheat, barley and other cereal-based feed.
2. For biochemical research.
3. It can be used as nutritional supplements. Requirement amount (mg/k/D): 60 to 87 for children, 310 to 560 for adults with great variance and is still affected by total protein in food and amino acids.
4. The first limiting amino acid for rice, wheat, bread, corn, etc. is glycine, which may be supplemented with a secondary restricted amino acid, threonine. It can still strengthen the peanut powder, oats and so on.
5. In order to exert the best efficacy, it can be co-used with glycine in rice, and co-used in wheat flour together with glycine and valine, and co-used with glycine and methionine in barley, oats, and co-used with glycine and tryptophan in corn.
6. It is easy to produce coke aroma and chocolate aroma upon co-heating with glucose. It has aromatherapy role.
7. L-threonine ([72-19-5]) is essential amino acids with the physiological effect of DL-threonine being half of that of the L-threonine. Upon its lack, people is easily susceptible to loss of appetite and fatty liver embolism. Threonine can not be de novo synthesized inside the higher animals body and must be supplied externally. The cereal protein, in addition to should being provided of L-lysine, should also be supplied with L-threonine. This is due to that although there is a high content of L-threonine, but the combination of threonine and peptide in the protein is difficult to be hydrolyzed and is not easily digested and absorbed. As a nutritional supplement, in order to play the best use of fruit, it can be co-used with glycine in the rice, co-used with glycine and valine in wheat flour, and co-used with glycine and methionine in the barley, oats as well as co-used with glycine and tryptophan in corn. Co-heating with hot grapes can easily produce empyreumatique and chocolate flavor with aromatherapy role. It can also be used for separation to obtain L-threonine and further for the preparation of amino acid infusion and integrated amino acid preparations.
