l-threonine is classified as an essential amino acid. humans do not synthesize l-threonine, so it must be obtained through the diet. the male adult’s daily requirement is 7 mg per kg of body weight. most people will get sufficient l-threonine through the diet, but as threonine content in grains is low, vegetarians are more likely than others to have deficiencies and should consider supplementation.
l-threonine is a key component of collagen, elastin and enamel proteins. it aids in proper fat metabolism in the liver; nutrients are more readily absorbed when threonine is present. l-threonine also helps the digestive and intestinal tracts function more smoothly. experts believe that l-threonine enhances the immune system by aiding in the production of antibodies.
applications:
l-threonine is an essential amino acid, mainly used in pharmaceutical, chemical reagents, food fortifiers, and feed additives. in particular, the amount used in feed additives grows rapidly. l-threonine with the feed has the following characteristics: ① can adjust the amino acid balance in the feed to promote livestock growth; (2) to improve the meat; (3) improve the nutritional value of amino acid with low digestion rate ④ can reduce feed raw material costs; in the eu (mainly germany, belgium, denmark, etc.) and the american states, it has been widely used in feed industry.
