Threonine is
an important nutritional enhancer, which can strengthen grains,
pastries and dairy products. Like tryptophan, threonine can restore
human fatigue and promote growth and development. In medicine,
because the structure of chemicalbook threonine contains hydroxyl
groups, it has a water holding effect on human skin, combines with
oligosaccharide chains, plays an important role in protecting cell
membrane, and can promote phospholipid synthesis and fatty acid
oxidation in vivo.
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.
