Odorless, slightly sweettaste. It melts and decomposes at 253. It decomposes with dilute alkali at hightemperature, and decomposes gradually with acid. Soluble in water, insoluble inethanol, ether or chloroform. Isoelectric point is PH6.16Applications:1) Threonine is an important kind of analeptic, which fortifies cereal, pastry anddairy products. Similar to tryptophan, it rejuvenates human bodies and promotesthe growth of infants. When applied in pharmaceutical field, threonine can moistenhuman skins due to the hydroxy in its structure2) Combined with oligose, it protects human cell membranes, and accelerates the synthesisof phosphatide and oxidation of fatty acid3) With a medicinal effect of preventing fatty liver, threonine preparation worksas a component of compound amino acid injection4) Meanwhile, threonine can be used for the production of monobactams, one of higheffect and low-allergy antibiotics5) As amino acid for forge, threonine is widely added in the forage for newborn pig,covering pig, poultry, shrimp, and eel. It can:a) Keep the balance of amino acids in forage and stimulate the growth of animalsb) Improve the meat qualityc) Increase the nutritive value of forage raw materials, which have low aminoacid digestibilityd) Apply to the production of low-protein foragee) Cut down the cost of raw materials for foragef) Decrease the nitrogen content in excrement and urine of animals, so that therelease of ammonia is slowed and the ammonia concentration is kept low in animalshedSpecifications:Chemical formula: C4H9NO3Molecular weight: 119.12Appearance White or light-brown crystal or powderLoss on drying: 1.0% Max.Residues on ignition: 0.5% Max.Assay: 98.5% Min.Specific rotation -26.7 -29.6Heavy metals 10PPM Max.Arsenic: 2PPM Max.pH: 5.0-6.5Packing:25kg/compound bag
