L-Threonine, CAS No.72-19-5, a essential amino acid amino acid manufactured through fermentation process. L-threonine function: a key component of collagen, elastin and enamel proteins. It aids in proper fat metabolism in the liver; nutrients are more readily absorbed when threonine is present. L-threonine also helps the digestive and intestinal tracts function more smoothly. Uses: L-Threonine is used in animal feed, poultry feed and food nutrition supplements. In cosmetics and personal care products, the function as hair conditioning agents and skin conditioning agents â?? miscellaneous.
As an experienced L-Threonine manufacturer and supplier, we has been supplying and exporting L-Threonine for almost 10 years, please be assured to buy from us. Any inquiries about price and the market trend please feel free to contact us, we will reply you within 1 working day.

L-Valine powder, CAS No.72-18-4, essential amino acid manufactured by fermentation from carbohydrate sources. No materials of animal origin are used in the production of L-valine. Along with L-leucine and L-isoleucine, is part of the branched chain of amino acids (BCAAs). L-valine is a branched chain amino acid (as are L-isoleucine and L-leucine), which is important for supplying energy to muscles. The branched chain amino acids enhance energy, increase endurance and aid in muscle tissue recovery and repair. Branched chain preparations are used in sports nutrition and health foods. As an experienced L-Valine manufacturer and supplier, we has been supplying and exporting L-Valine for almost 10 years, please be assured to buy from us.

The primary use of Ammonium Sulphate is as a fertilizer for alkaline soils. In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth. The main disadvantage to the use of Ammonium Sulphate is its low nitrogen content relative to Ammonium Nitrate, which elevates transportation costs. It is also used as an agricultural spray adjuvant for water soluble insecticides, herbicides, and fungicides. There it functions to bind iron and calcium cations that are present in both well water and plant cells. It is particularly effective as an adjuvant for 2,4-D (amine), glyphosate and glufosinate herbicides.
