Applications
<P class=tgt>Because Sue saddle acid molecule has 2 asymmetric carbon atoms, reason has the d-dimer threonine, L - threonine, D - don't threonine and L - don't threonine 4 kinds of optical isomers. Which form the protein's amino acids for L - threonine, other three kinds of optical isomers all cannot don't use. </P> <P class=tgt>DL - threonine for white crystalline or crystalline powder, odurless, taste slightly sweet. Melting point about for 245 ℃ (breakdown). Soluble in water (20.1 g / 100mL canister, 25 ℃), soluble in ethanol, and other organic solution. Chemical stable performance. Rat intraperitoneal injection LD505.355 g/kg (D type). </P> <P class=tgt>L - threonine [72-19-5] melting point is about 256 ℃ (breakdown), physiological effect for DL type 2 times of rat intraperitoneal injection LD503.094 g/kg. The rest with DL type. L - threonine ([72-19-5]) for the essential amino acids, DL - threonine physiological utility for L - threonine 1/2, lack of when susceptibility inappetence, such as fatty liver disease, Sue beauty in the higher animals, the body doesn't peptide synthesis, must by in vitro supply. Cereal protein except should be added n-acetylcysteine lysine outside, secondly namely is L - threonine. This is because L - threonine content is more, but the protein peptide and peptide sino-soviet combination of difficult hydrolysis. To digest absorb be caused by. As nutrition supplements, to achieve the best thickening into fruit, can use with glycine were used for rice, and glycine and valine, and were used in wheat flour glycine and methionine Shared barley, oats, with glycine and tryptophan were used for corn. And the grapes were hot easy generation malt and the smell of chocolate. Have increase incense role. Also used to fold TNSS must L - that makes amino acid threonine infusion and comprehensive amino </P>
