Feed Additive D (+) -Tryptophan CAS 153-94-6

Product Description

D-Tryptophan (English D(+)-Tryptophan) is a white or off-white to slightly yellow crystalline powder at room temperature. It is odorless or slightly odorless and has a slightly sweet taste. Solubility in water is 1.14g (25ºC), soluble in dilute acid and dilute alkali, stable in alkali, decomposed in strong acid, and plays an important role in the growth and metabolism of humans and animals. It is called the second essential Amino Acid, and L The physical and chemical properties of -types are almost the same, only the optical rotation is opposite, but their distribution, functions and coenzymes are diverse, and the melting point is very high, generally above 200 degrees, soluble in water, and absorbs light in the near ultraviolet region. Ability.

Application of Vanillin

As a non-protein active amino acid, D-tryptophan has special physiological properties
In the food and feed industry and agriculture, it can be used as a non-nutritive sweetener, Feed Additive, plant growth agent,
In the pharmaceutical industry, it is mainly used to synthesize various peptides instead of L-tryptophan to extend the half-life of peptide drugs and reduce side effects, without causing drug resistance and becoming an important synthetic precursor for enzyme inhibitors.
It can improve the body's immunity and delay the occurrence of allergic reactions. Most peptide antibiotics can resist gram-positive bacteria, and some have good inhibitory or killing effects on gram-negative bacteria such as Pseudomonas aeruginosa, mycobacterium, fungi, germs, germs and tumor cells.
Using D-tryptophan to synthesize a semi-synthetic antibiotic, its side chain plays an important role in its pharmacological function. The peptide bond is difficult to be acted on by β-lactamase, so it has high stability and a broad antibacterial spectrum. Low toxicity, low allergy, fast absorption, high blood concentration, long duration of medicine, etc.
