Threonine is an important nutrient enhancer, it can keep water of the human skin. it can promote phospholipid synthesis and fatty acid oxidation in the body, it is a composite of compound amino acid infusion.
Threonine is raw material of creating a class of high efficiency and low allergy antibiotics - single amide streptozotocin.

【Package and storage】：
Sealed by edible polyethylene bags and packed with paper board drum, the net weight of every drum is 25 kg / drum,It can be packed based on requirement.
It should be loaded and unloaded carefully, should prevent the sun and rain, it is can not be transported mixed with the toxic and hazardous substances; It’s nondangerous product, it should be sealed to store.
Function:
It’s an essential amino acid for human body, people will become to be lean or dead when lack of it.
Application:
1. Threonine is an important nutrient enhancer, which has the effect of recovering human fatigue and promoting growth.;
2. In medicine, because its structure contains threonine hydroxyl, it can keep water of the human skin.If it is combined with the oligosaccharide chains, it will play an important role in protecting cell membranes, it can promote phospholipid synthesis and fatty acid oxidation in the body, and its preparation has medicinal efficacy for promoting human development and anti- lipotropic, it is a composite of compound amino acid infusion.
3. Threonine is raw material of creating a class of high efficiency and low allergy antibiotics - single amide streptozotocin.
