Introduction
DL-Threonine is a non-essential amino acid, which is obtained by the synthesis of threonine catalyzed by soybean soybean enzyme. It is a white crystalline powder with a sweet taste that dissolves in water. DL-threonine has a double phototropic nature that can rotate light, and it contains two isomers of D-threonine and L-threonine, which is called DL-threonine.
The preparation method of DL-threonine is mainly by enzymatic synthesis. The soybean soybean soybean enzyme catalyzes the synthesis of DL-threonine, two reactants of D-threonine and L-threonine. This method is efficient, environmentally friendly, does not require the use of organic solvents, and has good yields and purity.
DL-Threonine is relatively safe under general conditions of use.
