      DL-Methionine Detail  


    Uses
    DL-methionine can be used as a nutritional supplement. It has the same physiological effects as L-methionine, but the price is low (L-type is made from DL-type), so generally chemicalbooks use DL-methionine. It can be used to improve the balance of amino acids in plant foods such as oats, rye, rice, corn, wheat, peanut powder, soybeans, potatoes, spinach, etc.
    Uses
    It is suitable for preventing and treating liver diseases and poisoning by arsenic or benzene, and can also be used to treat malnutrition caused by insufficient protein after dysentery and chronic infectious diseases. Uses: Nutritional supplement. It has the same physiological effects as L-methionine, but the price is low (L-type is made from DL-type), so generally DL-methionine is used. It is a limiting amino acid in plant foods such as oats, rye, rice, corn, wheat, peanut powder, soybeans, potatoes, spinach, etc. It is added to the above foods to improve the balance of amino acids. The required amount varies with the intake of cystine. The required amount for adult men is 1.1g/d. The taste of sea urchin is related to methionine, the sweetness of sea urchin is related to glycine and alanine, the bitterness is related to valine, and the umami taste is related to glutamic acid, so these amino acids can be prepared into seasonings. It is also used for amino acid infusion and comprehensive amino acid preparations. According to my country's GB2760-86 regulations, it can be used as a spice.
    Uses
    The content of commercial methionine is ≥98.5%. It is one of the amino acids necessary for the growth of poultry and livestock. It is the "skeleton" amino acid for biosynthetic protein. It has a strong regulatory effect on animal metabolism and is widely used in medicine, food, feed and cosmetics. In medicine, it can be used as the main component of amino acid infusion and compound amino acid, and can also be used to synthesize medicinal vitamins. Its anti-fatty liver effect can be used to produce liver protection preparations; in food, it is used for amino acid fortification of food and processing of food health products, and can be used as a nutritional supplement. Due to its special smell, it is only used in fish cake products; in the feed industry, methionine is used in the largest amount, used as a nutritional fortifier of feed, and a feed additive to make up for the balance of amino acids. Among the varieties of amino acid nutritional feed additives, methionine accounts for 60%, lysine accounts for 30%, and other amino acids account for about 10%.
    Uses
    DL-methionine is a feed nutritional fortifier. Lack of methionine in livestock and poultry can cause stunted development, weight loss, weakened liver and kidney function, muscle atrophy, fur deterioration, etc. Adding 1kg of methionine to feed is equivalent to the nutritional value of 50kg of fish meal. The general addition amount in feed is 0.05%-0.2%.
    Uses
    DL-methionine can be used as a biochemical reagent, biochemical research; used for the culture of mammals and insect cells where mixed isomers are marked.
