Product Description

Detailed introduction to L-Threonine(Feed Grade):
Structure and Properties
  Name: L-Threonine(β-hydroxyl-αaminobutyric acid)
  CAS NO: 72-19-5
  Structural Formula:

  Molecular weight: 119.12
  Properties: White orthorhombic or crystalline powder. Odorless, Slightly-sweet taste. It melts and decomposes at 253.It decomposes with dilute alkali at high temperature.it decmposes gradually with acid.Soluble in water Insoluble in , ether or chloroform.Isoelectric point is PH 6.16.

Application

As amino acid for forge,threonine is widely added in the forage for newborn pig,covering pig,poultry,shrimp,eel and so.It can:
  --Keep the balance of amino acids in the forage and stimulate the growth of the animals;
  --Improve the meat quality;
  --Increase the nutritive value of forage raw materials which have low amino acid digestibility;
  --Apply to the production low-protein forage;
  --Cut down the cost of raw materials for forage;
  --Decrease the content in the excrement and urine of animals so that the release is slowed and the concentration is kept low in animal shed.

ECHEMI Editorial Reference

L-Threonine is a natural amino acid, can be produced by microbial fermentation, and is used in food, medicine, or feed[1].
Solid|White crystalline powder; slight savoury aroma
L-threonine is an optically active form of threonine having L-configuration. It has a role as a nutraceutical, a micronutrient, a Saccharomyces cerevisiae metabolite, a plant metabolite, an Escherichia coli metabolite, a human metabolite, an algal metabolite and a mouse metabolite. It is an aspartate family amino acid, a proteinogenic amino acid, a threonine and a L-alpha-amino acid. It is a conjugate base of a L-threoninium. It is a conjugate acid of a L-threoninate. It is an enantiomer of a D-threonine. It is a tautomer of a L-threonine zwitterion.|An essential amino acid occurring naturally in the L-form, which is the active form. It is found in eggs, milk, gelatin, and other proteins.|Threonine is an essential amino acid in humans (provided by food), Threonine is an important residue of many proteins, such as tooth enamel, collagen, and elastin. An important amino acid for the nervous system, threonine also plays an important role in porphyrin and fat metabolism and prevents fat buildup in the liver. Useful with intestinal disorders and indigestion, threonine has also been used to alleviate anxiety and mild depression. (NCI04)
