Dl-methionine powder Usage and Synthesis.

DL-methionine is an important amino acid that is widely used in animal husbandry and agriculture. It can help farmers reduce the crude protein content in diet formulation without affecting animal performance, thus significantly reducing nitrogen excretion and greenhouse gas emissions.

In addition, DL-methionine is also used in the production of PPS materials, which are widely used in wind power generation to help convert wind power into electricity.

In the production process, DL-Methionine can be produced by a combination of organic synthesis and chemical engineering or by biofermentation.

Although there is currently an overcapacity of methionine, there are differences between DL-methionine and hydroxymethionine, with hydroxymethionine having advantages in terms of storage and transportation, environmental protection and technological advantages.

What is DL-Methionine?

DL-Methionine is the synthetic form of methionine, a sulfur-containing essential amino acid. Animals cannot synthesize it themselves and must obtain it from their diet.

"DL" indicates that it is a mixture of D-methionine (dextrorotatory) and L-methionine (levorotatory). The key point is that enzymes in the animal's body can convert D-methionine into L-methionine (the biologically active form), therefore DL-methionine has 100% biological efficacy.

Main Functions:

• Protein Synthesis: A crucial component in building muscle, feathers, and tissue proteins.
• Methyl Donor: Participates in various important biological methylation reactions, affecting lipid metabolism, DNA expression, and immune function.
• Precursor: A prerequisite for the synthesis of active substances such as taurine, glutathione, and cysteine, and is related to antioxidant capacity and detoxification processes.

Uses and functions of Dl-methionine powder.

DL-Methionine can be used as a nutritional supplement. It has the same physiological effect as L-type methionine, but is less expensive (L-type is made from DL-type), so DL-methionine is generally used. In oats, rye, rice, corn, wheat, peanut flour, soybeans, potatoes, spinach and other plant foods to improve amino acid balance.

Suitable for the prevention and treatment of liver disease and arsenic or benzene poisoning, can also be used in the treatment of dysentery and chronic infectious diseases caused by protein deficiency and malnutrition

DL-Methionine can be used as a biochemical reagent, biochemical research; for mixed isomers are labeled mammalian as well as insect cell culture applications.

Product Method of Bulk Dl-methionine powder.

D-configuration and L-configuration of methionine with the same physiological effect, mostly DL-type, so it is favorable to manufacture by synthetic method. It is generally produced by reacting acrolein with methyl mercaptan.

Frequently Asked Questions about DL-Methionine

Q1: What is the difference between DL-Methionine and L-Methionine? Is it effective for animals?

A: L-Methionine is the biologically active form. DL-Methionine is a mixture of D- and L-forms. Because animals possess D-amino acid oxidases, which efficiently convert the D-form to the L-form, DL-Methionine has complete biological efficacy (100%), making it the most economical and effective choice in the feed industry. Pure L-Methionine is expensive and mostly used in pharmaceuticals or certain pet foods.

Q2: Why is adding DL-Methionine considered environmentally friendly?

A: Because it allows nutritionists to reduce the total crude protein content in feed while maintaining an ideal amino acid balance. Excess protein not utilized by animals is excreted as nitrogen (mainly from urea and ammonia). Reducing nitrogen excretion directly reduces the risk of eutrophication pollution in soil and water bodies, aligning with the principles of circular agriculture.

Q3: How to determine the amount of DL-Methionine to add to feed?

A: The dosage is based on:

* Animal breed, growth stage, and production goals (e.g., weight gain, egg production).

* The methionine analysis value of the basal diet (corn, soybean meal, etc.).

* Accepted animal nutritional requirements standards (e.g., NRC, 2012; Evonik AMINOChick/AA pig®). It must be calculated by a professional animal nutritionist using formulation software.

Q4: Is DL-Methionine safe? Are there any side effects?

A: When used according to the recommended nutritional levels, DL-Methionine is very safe for animals. It is an essential nutrient for animals, not a drug. Excessive addition (far exceeding requirements) may theoretically cause amino acid imbalances or increase metabolic burden, but this rarely occurs in regulated feed production.
