Use
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, because the structure of threonine contains hydroxyl groups, it has a water-holding effect on human skin, binds to oligosaccharide chains, plays an important role in protecting cell membranes, and promotes phospholipid synthesis and fatty acid oxidation in the body.
Used in biochemical research, as an amino acid nutrition medicine in medicine, mainly used to treat anemia. Use amino acid medicine. Mainly used in amino acid infusion, comprehensive amino acid preparation, food nutrition enhancer. Lack of threonine can cause loss of appetite, weight loss, fatty liver, testicular atrophy, staining changes in the anterior pituitary cells and affect bone development. Adverse reactions taboo: when an adult instills 22.5g once, it can cause fever, headache and other adverse reactions.
Nutritional supplements. In addition to supplementing L-lysine, cereal protein is also L-threonine. This is because although the content of L-threonine is high, the combination of threonine and peptide in protein is difficult to hydrolyze, and it is difficult to digest and absorb. It is also used to prepare amino acid infusion and comprehensive amino acid preparations.
