D- tryptophan
Alias: D-TRP
D(+)-TRYPTOPHAN
D-TRYPTOPHAN
D-TRYPTOPHANE
D-2-AMINO-3-(3-INDOLYL)PROPIONIC ACID
D-2-AMINO-3-INDOLEPROPIONIC ACID
D-2-AMINO-3-INDOLYLPROPANOIC ACID
D-ALPHA-AMINO-3-INDOLEPROPIONIC ACID
CAS: 153-94-6
Molecular Formula:C11H12N2O2
Molecular weight: 204.23
EINECS number: 205-819-9
Appearance : white or yellowish crystalline powder
Content 99.0%~101.0%
The light transmittance of more than 95%
Acidity PH 5.5 ~ 6.4
Dry weight loss is less than 0.2%
Burning residue is less than or equal to 0.1%
Chloride [Cl-] is less than or equal to 0.02%
Sulfate [SO42-] = 0.02%
Ammonium [NH4+] = 0.02%
The heavy metal [Pb] is less than or equal to 10ppm
With [Fe] = 10ppm
Arsenic salt [As2O3] = 1ppm
Usage: the important nutrition agent, medicine, used as laipi disease prevention and control agent
D-TRYPTOPHAN as a non protein amino acid, with special physiological properties, in the food and feed industry and trade industry and agriculture can be as non nutritive sweeteners, feed additive, plant growth agent, in the pharmaceutical industry, mainly used for various synthetic peptides, instead of L-tryptophan extended peptide drugs.The half-life of the object and the side effects of the drug are not to be the important precursors of the enzyme inhibitor. Can improve the body's immune ability, delay the occurrence of allergic reactions. Mostly multiple peptide antibiotics against gram positive bacteria and some gram negative bacteria such as Pseudomonas aeruginosa bacteria, mycobacteria, fungi, bacteria, pathogens and tumor cells have better inhibition or killing effect. D-TRYPTOPHAN synthesis of semi synthetic antibiotics, the side chain for its pharmacological function plays an important role peptide bond is very difficult to be beta in acid and enzyme action, in order to have a higher stability
Of, and has wide antibacterial spectrum, low toxicity, low allergic, fast absorption, high blood concentration, a long time.
The production method is based on the DL- tryptophan as raw material, and the cooling condition is added to the reaction of the chloride, and then the water is re crystallized in the ice water, and then the water is filtered.Treatment, removal of L- type, acetic acid, ethanol heavy crystallization refined.
