Application: The structure of threonine contains hydroxyl group, which has water-holding effect on human skin. It binds to oligosaccharide chain and plays an important role in protecting cell membrane. It can promote phospholipid synthesis and fatty acid oxidation in vivo. Its preparation has the medicinal efficacy of promoting anti-fatty liver development in human body and is a component in complex amino acid infusion. At the same time, threonine is the raw material for the manufacture of a class of highly effective hypoallergenic antibiotics, monoamidin.
What is Threonine?
Threonine (symbol Thr or T) is an amino acid that is used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated −NH+
3 form under biological conditions), a carboxyl group (which is in the deprotonated −COO− form under biological conditions), and a side chain containing a hydroxyl group, making it a polar, uncharged amino acid. It is essential in humans, meaning the body cannot synthesize it: it must be obtained from the diet. Threonine is synthesized from aspartate in bacteria such as E. coli. It is encoded by all the codons starting AC (ACT, ACC, ACA, and ACG).
