Product Introduction:

L-methionine, also known as S-methionine, is the levorotatory form of methionine, the chemical formula is C5H11NO2S, and its chemical properties are colorless or white glossy flake crystals or white crystalline powder, with a slightly special odor and slightly bitter taste.

Soluble in water (5.6g/100mL, 30℃), warm dilute ethanol, alkaline solution or dilute mineral acid, hardly soluble in ethanol, almost insoluble in ether.

L-Methionine is a crucial amino acid for animal as well as human nutrition. It is frequently utilized in the preparation of substance amino acid infusions, as a medicine for the therapy of intense liver disease and liver cirrhosis, and also as an antidote for medications.

L-Methionine is just one of the eight amino acids that the body requirements but can not synthesize on its own. It is widely made use of in numerous fields such as amino drinks, food, biochemical reagents and life.

DL-methionine is commonly utilized in compound feed for hens, pigs as well as cattle.

Its metabolic rate is connected to cysteine, and also in prokaryotes formylated methionine is the starting amino acid for healthy protein biosynthesis.

It can in addition be activated by ATP along with exchanged s-adenosylmethionine, which is used as a methyl contributor to take part in the synthesis of creatine and choline.

Uses of L-methionine:

L-Methionine is presently widely made use of in the fields of medicine, food, feed as well as cosmetics.

Among Them in Medical

  • L-Methionine can be made use of as the major element of amino acid infusion and substance amino acids, and can also be used to manufacture vitamins. It can be utilized to generate liver defense preparations by utilizing its anti-fatty liver effect.

In Food

  • l-Methionine can enhance the nutritional value of food, in all sort of food and also drinks, such as: bread, ice cakes, fruit tea, dairy products, soft drinks, sorbet, and so on.
  • The addition of alanine can boost the usage of protein in food and drinks, and also due to the fact that alanine has the attributes of being directly taken in by cells.
  • It is also used to improve the taste of artificial synthetic sweeteners, which can raise the sweetness and also minimize the dosage.

In Feed

  • In addition, L-Methionine has a strong regulatory effect on the metabolism of animals, so it is widely used as a feed additive to improve feed quality, improve the utilization rate of natural protein and promote animal development.
  • For example, DL-methionine can increase the egg production of chickens, increase the weight of pigs, and increase milk production in dairy cows.
  • It can help animals grow rapidly in a short period of time, effectively increase the amount of lean meat, shorten the feeding cycle, and save 40% of the feed.
  • At the same time, L-Methionine is also involved in the transfer of methyl groups, the metabolism of phosphorus and the synthesis of epinephrine, choline and creatine in animals, and is also the raw material for the synthesis of protein and cystine.

Practical Applications of L-methionine:

Used as a food additive

  • l-Methionine can enhance the nutritional value of food, in all sort of food and also drinks, such as: bread, ice cakes, fruit tea, dairy products, soft drinks, sorbet, and so on.
  • The addition of alanine can boost the usage of protein in food and drinks, and also due to the fact that alanine has the attributes of being directly taken in by cells.
  • It is also used to improve the taste of artificial synthetic sweeteners, which can raise the sweetness and also minimize the dosage.

Used as a feed nutrient fortifier

    • L-methionine is mainly used as a feed nutrition enhancer. It is one of the essential amino acids for animal growth. It is the “skeleton” amino acid for protein biosynthesis.
    • It is the main donor of methyl groups in animals. It plays a certain role in the synthesis of choline and phospholipids in liver fat by adrenaline in the metabolic process of animals.
    • The lack of methionine in livestock and poultry can cause stunted growth, weight loss, weakened liver and kidney functions, muscle atrophy, and fur deterioration.

Used as an intensifier for protein feed

    • L-methionine is a sulfur-containing amino acid and is the second essential limiting amino acid for pigs. If lysine and methionine are properly added to the feed, it can effectively improve the utilization rate of feed protein.
    • Therefore, lysine and methionine are called protein feed enhancers.

Used as a catalyst

    • L-methionine plays an important role in the metabolism of the body. But its concentration in the body is not high. Although methionine is also easy to penetrate the blood-brain barrier, its concentration in the brain is lower than that of glutamic acid, glutamine, aspartic acid, alanine, glycine, serine and cattle.
    • The concentration of sulfonic acid in the cerebrospinal fluid is not high, and the concentration of L-methionine in muscle tissue is lower than the average value of other amino acids.

It is also a more effective antidepressant drug

    • Adenosylmethionine can also be used as a methyl donor, similar to the methylation reaction of L-methionine. Methylation causes normal brain components to become hallucinogenic substances.
    • Therefore, hypermethylation will involve schizophrenia, psychosis, depression and mental related diseases. Conversely, lack of methylation can be related to depression.

Antioxidant and antidote

    • It is transformed from L-methionine into cysteine, glutathione, and taurine, becoming the most powerful antioxidant and antidote for the human body.
    • Methionine is also considered an amino acid that promotes the increase of all amino acid levels in the body.
    • At the same time, it also promotes the absorption and transmission of important minerals of selenium and zinc, and the formation of choline; it is a member of the vitamin B family and lecithin, and is an important substance for the formation of acetylcholine as a neurotransmitter.
