Threonine (L-threonine) cannot be synthesized by animals itself, and it is an essential amino acid, one of the essential amino acids for the human body, and can be used to improve nutrition and improve physical fitness. Threonine is necessary to maintain nitrogen balance in the body and promote normal growth and development. Threonine is an important nutrient fortifier that can fortify cereals, cakes, and dairy products. Like tryptophan, it has the same effect of restoring body fatigue and promoting growth and development. In medicine, threonine 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.

Creative Proteomics can provide a method for the detection of amino acids by ion chromatography, which can quickly and quantitatively detect threonine and related threonine metabolites, ensuring that customers can provide highly sensitive and complete threonine detection reports. The method for detecting threonine is simple and does not require troublesome pretreatment or post-column processing. It realizes the rapid determination of threonine, facilitating the analysis of the functional mechanism of threonine in biological samples and the quantitative determination and analysis of threonine in amino acid-added related products.
