      Product Application  


    (1) Feed industry: It is an important additive in animal feed. It can balance amino acids, promote the growth and development of animals, increase the lean meat rate, enhance the disease - resistance ability, and improve the feed utilization rate. For example, adding it to pig feed can accelerate the growth rate of pigs.

    (2) Pharmaceutical industry: It can be used to synthesize medicinal amino acid infusions and compound amino acid preparations. It also serves as a liver - protecting drug, which is used to assist in the treatment of liver diseases such as liver cirrhosis and fatty liver. It is also helpful in the treatment of poisoning caused by arsenic, benzene, etc.

    (3) Food industry: As a nutritional fortifier, it is added to foods such as bread and biscuits to improve the utilization rate and nutritional value of protein, meeting the nutritional needs of special groups.

    (4) Cosmetics industry: It is often used in skin - care products. It has the functions of moisturizing and antioxidation, which can protect the skin, reduce the formation of wrinkles, and delay skin aging.


      Product Function


    (1) Involved in protein synthesis: As an essential amino acid for the human body, it is an important raw material for protein synthesis. It participates in the synthesis of various proteins in the body, which is crucial for maintaining normal physiological functions, growth and development, and tissue repair.

    (2) Methyl donor: In the process of metabolism in the body, it can provide methyl groups and participate in many biochemical reactions involving methylation, such as the methylation modification of DNA, RNA, and proteins. These modifications have important effects on processes such as gene expression regulation and cell signal transduction.

    (3) Regulating fat metabolism: It helps with the metabolism and transport of fat in the liver, preventing the accumulation of fat in the liver, and playing a certain role in the prevention and improvement of diseases such as fatty liver.

    (4) Antioxidant effect: It can be converted into cysteine, which in turn participates in the synthesis of glutathione. Glutathione is an important antioxidant in the body, which can scavenge free radicals and protect cells from oxidative damage.

    (5) Detoxification function: It can combine with certain harmful substances to promote their excretion from the body, playing a detoxification role. For example, it has a certain detoxification effect on heavy metal ions and drugs.
