L-Threonine is an essential amino acid that helps to maintain the proper protein balance in the body. It is important for the formation of collagen, elastin, and tooth enamel, and aids liver and lipotropic function when combined with aspartic acid and methionine

Threonine is the third limiting amino acid in corn-soybean meal poultry rations . At protein levels typically used, however, diets composed mainly of corn and soybean meal are not limiting in threonine. Threonine, like lysine, is limiting in most cereals.

Threonine is an essential amino acid. Amino acids are the building blocks the body uses to make proteins. The "essential" amino acids are those that cannot be made by the body and must be obtained from the diet.

Amino acid metabolism involves: 1) protein synthesis and degradation, 2) incorporation of amino acid nitrogen into uric acid, 3) conversion of amino acid carbon skeletons into glucose, fat, energy, or C02 and H20, and 4) formation of non-protein derivatives. Threonine participates in protein synthesis, and its catabolism generates many products important in metabolism (i.e., glycine, acetylCoA, and pyruvate). Poultry are not capable of synthesizing threonine de novo which makes it a nutritionally essential amino acid. Threonine (2-amino-3-hydroxybutyric acid, QH9N03) has a molecular weight of 119.12 and contains 11.76% nitrogen.  

Because threonine, unlike most amino acids, is not transaminated, animals do not utilize its D-isomer and a-keto acid. DL-threonine has both a and /3 carbons, which are asymmetric and can yield four isomers: L (2S, X), D (2R, 3R), L-all0 (2S, 3R), and D-allo (2R, 3s). Baker [5, 61 suggested that DL-threonine should provide no more than 25% biological activity, which is based upon one-fourth of the molecule being L-threonine. Thus, poultry can utilize only L-threonine.
