L-Threonine Powder Usage and Synthesis.

Threonine is an amino acid that cannot be synthesised by animals themselves but is very much needed. It can be used to precisely balance the amino acid composition of feeds, meet the needs of animal growth and maintenance, increase weight gain and lean meat ratio, and reduce the feed-to-meat ratio.

L-Threonine can be used to accurately balance the amino acid composition of feed to meet the growth and maintenance needs of animals, increase weight gain and lean meat ratio, and reduce the feed-to-meat ratio; it can improve the nutritive value of feed materials with low amino acid digestibility, and improve the production performance of low-energy feeds; it can reduce the level of crude protein in feeds, and improve the utilisation rate of nitrogen in feeds, and reduce the cost of feeds; and it can be used in the rearing and culture of swine, chickens, ducks, and high-level aquatic products.

L-Threonine is a feed additive produced by adopting the principle of bioengineering, using corn starch and other raw materials through deep liquid fermentation and refining.

It can adjust the balance of amino acids in feed, promote growth, improve meat quality, improve the nutritional value of feedstuffs with low amino acid digestibility, produce low-protein feeds, help to save protein resources, reduce the cost of feedstuffs, reduce the nitrogen content of livestock and poultry faeces and urine, and the concentration of ammonia in the livestock and poultry houses and the release rate.

It is widely used to add piglet feed, breeder feed, broiler feed, shrimp feed and eel feed.

Uses and functions of L-Threonine.

Nutritional supplements. Cereal proteins need to be supplemented with L-lysine, followed by L-threonine. This is due to the content of L-threonine is more, but in the protein threonine and peptide binding is difficult to hydrolyse, not easy to digest and absorb.

It is also used to formulate amino acid infusion and comprehensive amino acid preparation.

Amino acid drugs. Mainly used in amino acid infusion, comprehensive amino acid preparation, food nutritional fortifier. If the lack of threonine will cause loss of appetite, weight loss, fatty liver, testicular atrophy, anterior pituitary cells staining changes and affect bone development.

Adverse reactions and contraindications: Adults can cause fever, headache and other adverse reactions when 22.5g is injected at one time.

Threonine is an important nutrient fortifier that fortifies cereals, pastries, and dairy products, and like tryptophan has the effect of restoring fatigue and promoting growth and development.

Pharmaceutically, due to the hydroxyl group in the structure of threonine, it has a water-holding effect on human skin, combines with oligosaccharide chains, plays an important role in protecting cell membranes, and promotes phospholipid synthesis and fatty acid oxidation in the body.

Physiological Function of L-Threonine.

Amino acids are the building blocks of proteins, which are made up of peptides, whose peptide chains are made up of amino acids. Different proteins are made up of peptide chains with different sequences and lengths of amino acids. Genes related to heredity are actually chains of amino acids in different order.

Currently, there are a total of 28 amino acids relevant to the human body. Of these 28 amino acids, 9 (about 32%) are required to be supplied directly from amino acids in dietary proteins and cannot be synthesised in the body from other amino acids in the proteins consumed.

They are leucine, isoleucine, valine, lysine, methionine, tryptophan, threonine, phenylalanine and histidine. Of these, histidine is still under debate.

It is generally accepted that histidine is an essential amino acid for infants and young children under 4 years of age, and is synthesised on its own at older ages. Non-essential amino acids are not unimportant; sometimes they are more important than essential amino acids.

Taurine, arginine, and glutamine, for example, are so important in certain diseases or stressful conditions that they are called conditionally essential amino acids. Threonine is an essential amino acid that helps the body maintain protein balance.

It plays a role in the formation of collagen and elastin. Threonine is anti-fatty liver when combined with aspartic acid and methionine. Threonine is found in the heart, central nervous system and skeletal muscles and prevents the accumulation of fat in the liver.

It boosts the immune system by promoting the production of antibodies. Threonine is low in cereals and therefore vegetarians are susceptible to threonine deficiency.

Pharmacodynamics of  Bulk L-Threonine Powder.

Method I. Direct fermentation method

Using glucose as raw material, selective breeding of nutritionally deficient type cum feedback inhibition and deterrence in the synthesis of structural analogues to achieve L-threonine acid production rate of 18g/L,Corynebacterium glutamicum, acid production rate of 14g/L,Mucilage racemosae rate of 14g/L. Glucose [Pseudobacillus yellows, Corynebacterium glutamicum, Mucilage racemosae, etc.] → L-Threonine

Method two, chemical synthesis method

Threonine obtained due to chemical synthesis is a mixture of four optical isomers, i.e. DL-threonine. One of the amino acids constituting the protein is L-type threonine, so it is necessary to separate the threonine body from the aliquot, and then further optical isomer splitting, in order to get L-threonine.

With copper glycinate and acetaldehyde under alkaline conditions, a similar hydroxyl aldehyde condensation reaction occurs, the synthesis of copper threonate threonate threonate and alloys two mixtures of copper threonate, according to its stability and solubility of the different, after the de-coppering can be separated out of threonate DL-Threonine, and the final splitting to get L-Threonine.
