Applications

Purity: 98%. For white sheet-shape crystallization or crystalloid powder, especially smelly, sweet. Mp280 282 ℃ (breakdown), votes-free of thermal and light stability, air stable, acid unstable, can lead to take off methyl role. Soluble in water (3.5%, 25 ℃), dilute acids and dilute alkali solution, and very difficult to soluble in ethanol, insoluble in ether. Isoelectric 5.74. Amino acids drugs, increase nutrition supplements. Used for cirrhosis and fatty liver. Besides large used for feed additive, to improve quality and improve the natural protein feed utilization ratio and the promoting development of animal. Such as DL - methionine can raise chicken eggs, make the pig weight gain, the cows are prolific milk, etc. Adverse reaction: hepatic coma jiyong. Increase nutrition supplements. One of the human body essential amino acid. Because the price higher than DL - methionine and effect are equal, reason often with DL - methionine. Used in biochemical research and increase nutrition supplements, also used for pneumonia, cirrhosis and fatty liver disease such as adjunctive treatment
