Description

Product Detail

Threonine

Threonine is an important additive in many animal feeds, particularly swine and poultry, but also plays an important role in companion animal feeds.

Pigs require proteins, polypeptides and amino acids in their diets in order to grow and to build muscle tissue. The protein components of corn and other cereal grains are deficient in threonine, so that protein-rich soybean meal is used in swine feed to increase the content of available amino acids.

An ideal formulation combines soybean meal and amino acids, based on the specific life cycle requirement of the species. For typical corn/soy-based diets for pigs, threonine is the “second-limiting,” or the second nutrient to limit the animal’s growth unless supplemented.

Similarly, for broiler chicken and laying hen diets, threonine is either the second- or third-limiting amino acid in corn/soy-based diets. Therefore, it is a critical additive for poultry diets as well.

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)
