DL-Methionine
Alias: (R,S)-2-Amino-4-methylsulfanyl-butyricacid
(RS)-2-Amino-3-methylthiobutansαure
4-Methylmercapto-2-aminobutyricacid
alpha-Amino-gamma-methylmercaptobutyric acid
Amurex
Banthionine
butanoicacid,2-amino-4-(methylthio)-,DL-
Cynaron
CAS : 59-51-8
EINECS : 200-432-1
Molecular formula: C5H11NO2S
Molecular weight: 149.21
Melting point 284 C (Dec.) (lit.)
Density :1.34
FEMA :3301
Storage condition :0-6 degrees
Solubility 1 HCl: M 0.5 at C 20 clear, M, colorless
The water solubility of 2.9 g/100 mL (20 degrees C)
Merck 145975
BRN 636185
Properties:DL- methionine from the alcohol to form a white sheet of crystalline or crystalline powder, slightly sweet, has a special smell. No opticity. Can dissolve in water, dilute acid and dilute alkali, slightly soluble in 95% alcohol, insoluble in ether.
Application :in the prevention and treatment of liver diseases and arsenic and benzene poisoning, can also be used for treatment of diarrhea and chronic infectious diseases due to protein deficiency caused by malnutrition
This is the use of feed nutritional supplements. The lack of methionine in livestock and poultry, can cause the development of bad, weight loss, liver and kidney function, muscle atrophy, fur, etc.. Feed additive 1kg methionine, the nutritional value of fish meal is equivalent to 50kg. Feed in general to add the amount of 0,05%-0.2%.
Usage:The physiological effect of L- type was same, but the price was low (L- type DL-), so it was generally used DL-. In oats, rye, rice, corn, wheat, peanut powder, soybean, potato, spinach and other plant foods are restricted amino acids. To improve the balance of amino acids in the food. Need to amount with the amount of ammonia acid intake Iso. Adult men need to amount to 1.1g/d. Sea urchin flavored with methionine, sea urchin sweetness and glycine, alanine, bitterness and valine, umami and glutamic acid, which can be the amino acid preparation seasoning into Agent.
It is still used in the synthesis of amino acid infusion, synthetic amino acid preparation.
According to the provisions of 2760-86 GB can be used as a spice.Commodity use methionine content is more than or equal to 98.5% is livestock animal growth, one of the essential amino acids, protein biosynthesis of amino acid is the "skeleton", on animal metabolism has a strong regulatory role, widely used in medicine, food, feed and cosmetics and other fields. Among them in medicine, can be used as the main component of amino acids infusion and compound amino acids
And for pharmaceutical synthesis of vitamin, using the anti fatty liver effect. It can be used for production of hepatoprotective preparation
in food for amino acid food fortified products and health food and industry and trade, and can be used as nutritional supplements, because of the special smell, so only for surimi product
in the feed industry and methionine maximum amount, used as feed nutrition fortifier, MI Amino acid balance of feed additives, in the amino acid type of feed additives in the varieties of the 60%, lysine, lysine 30%, other amino acids accounted for about 10%.
