L-Methionine CAS 63-68-3

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.
