DL-Methionine CAS No: 59-51-8 Molecular formula: C5H11NO2S Molecular weight: 149.21 Product standard: AJI-92/97 Version, EP-4 Version, USP-24/26 Version, FCC-4 Version Properties: White flaky crystal or crystalline powder. Has special smell. Slight sweet taste. Melting point: 281 degree C(decompound). 10% aqueous solution's pH value is 5.6-6.1. No optical rotation, stable to heat and air. Unstable to strong acid, can cause the demethylation. Soluble in water(3.3G/100ml, 25degree C), diluted acid and diluted alkali solution. Very hard to dissolve in ethanol, almost does not dissolve in ether. Use: DL-Methionine is one of the basic units for composing the protein, is the only sulfur bearing amino acid among the essential amino acids, it participated in the transmethylation interior the animal body, the phosphorus metabolism and the adrenalin, choline and creatine synthesis, it also is the raw material of the protein and cystine synthesis. Methionine is unable to synthesize in the animal body, must take in from food. Adds it in the feed, can promote the poultry to grow, increase lean meat quantity and reduce the feeding cycle.

Description Methionine is a sulfur-containing amino acid that is butyric acid bearing an amino substituent at position 2 and a methylthio substituent at position 4. It has a role as an Escherichia coli metabolite, a Saccharomyces cerevisiae metabolite, a plant metabolite, a Daphnia magna metabolite and an algal metabolite. It is an alpha-amino acid and a sulfur-containing amino acid. It derives from a butyric acid. It is a conjugate base of a methioninium. It is a conjugate acid of a methioninate. It is a tautomer of a methionine zwitterion.

DL-Methionine, Poultry Feed Supplements, Cattle Feed Additives, Animal Feed Amino Acids

Animal feed supplement for livestock is chelated by DL-methionine and zinc sulphate 1. Resulting from the reaction of a mole of zinc ion to a moles of methionine, high chelate percentage ,the greatest stability. 2. High bioavailability , better nutrition of zinc,is a kind of better feed additive 3. Don't be affected by pH value, inorganic ions and organic macromolecules in digestive tract. Higher utilization ratio [Product function] 1. The bioavailability of animal feed supplement for livestock significantly better than other organic zinc. 2. Solve the problem of hoof crack for sows efficiently . 3. Increase the laying, fertilization, and hatching rates, improve the quality of eggshell. 4. Leads to the removal of rough and messy feather, obtaining bright feather. And decrease in cannib alism of pecking the plume and anus. 5. Increase feed intake effectively , can improve animal growth and the resistance of disease.promote more nutrition 6.This zinc methionine can suplement animals nore nutrition healthy,can make the animals growth Specification of DL-Methionine: Items Specification(AJI92) Appearance White crystals or crystalline powder Assay(%) 99.0%~101.0% Heavy metal(Pb%) =0.002 Transmittance(%) =98.0 PH 5.6~6.1 Loss on drying(%) =0.3 Residue on ignition(%) =0.1 Chloride(Cl%) =0.02 Sulfate(SO4%) =0.02 Iron(Fe%) =0.001 Arsenic(As2O3%) =0.0001 Ammonium(NH4%) =0.02 Package:25kg Bag Or as requirement Usage: DL-Methionine is one of the basic units for composing the protein, is the only sulfur bearing amino acid among the essential amino acids, it participated in the transmethylation interior the animal body, the phosphorus metabolism and the adrenalin, choline and creatine synthesis, it also is the raw material of the protein and cystine synthesis.
