      L-Threonine Detail  


    Uses
    Threonine is an important nutritional enhancer that can enhance cereals, pastries, and dairy products. Like tryptophan, it can restore human fatigue and promote growth and development. In medicine, because threonine contains hydroxyl groups in its structure, it has a water-retaining effect on human skin. It combines with oligosaccharide chains and plays an important role in protecting cell membranes. It can promote phospholipid synthesis and fatty acid oxidation in the body.
    Uses
    It is used in biochemical research and as an amino acid nutrient in medicine, mainly used to treat anemia.
    Uses
    Amino acid drugs. Mainly used for amino acid infusion, comprehensive amino acid preparations, and food nutritional enhancers. Lack of threonine can cause loss of appetite, weight loss, fatty liver, testicular atrophy, chromatographic changes in anterior pituitary cells, and affect bone development. Adverse reactions and contraindications: When adults drip 22.5g at a time, it can cause adverse reactions such as fever and headache.
    Uses
    Nutritional supplement. In addition to L-lysine, cereal protein needs to be supplemented with 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 difficult to digest and absorb. It is also used to prepare amino acid infusion and comprehensive amino acid preparations.
    Uses
    One of the essential amino acids for the human body, it can be used to improve nutrition and physical fitness.
    Uses
    Biochemical research. Preparation of tissue culture medium
