Odorless, slightly sweettaste. It melts and decomposes at 253°C. It decomposes with dilute alkaliat high temperature, and decomposes gradually with acid. Soluble in water,insoluble in ethanol, 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 andpromotes the growth of infants. When applied in pharmaceutical field,threonine can moisten human skins due to the hydroxy in its structure2) Combined with oligose, it protects human cell membranes, and acceleratesthe synthesis of 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, oneof high-effect 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 inanimal shedSpecifications:1) Appearance: white or light-brown crystal or powder2) Loss on drying: 1.0% max.3) Residues on ignition: 0.5% max.4) Assay: 98.5% min.5) Specific rotation: -26.7 - 29.6 degree6) Heavy metals: 10PPM max.7) Arsenic: 2PPM max.8) PH: 5.0 - 6.5Packing:25kg/compound bag
