L-threonine ([72-19-5]) is an essential amino acid, and the physiological effect of DL-threonine is half that of L-threonine. Methine cannot be synthesized in higher animals and must be supplied in vitro. In addition to supplementing L-lysine, cereal protein is followed by L-threonine. This is because although the content of L-threonine is large, the combination of threonine and peptide in protein is difficult to be hydrolyzed. Difficult to digest and absorb. As a nutritional supplement, for optimal use of fruit, it can be used with glycine for white rice, with glycine and valine for wheat flour, with glycine and methionine for barley and oats, and with glycine and tryptophan for corn. It is easy to produce caramel and chocolate aromas when heated with grapes. Has a fragrance-enhancing effect. It is also used to prepare L-threonine by fractionation to prepare amino acid infusion and comprehensive amino acid preparations.
