  • Description

    Introduction

    Product properties: L-Proline is white crystalline powder and has characteristic sweet taste. It is one of the most important amino

    acids for synthesizing human protein. It is widely used in the food and medical industry, and is an important intermediate for

    synthesizing ACE inhibitors such as Captopril and Enalapril. It is also one of the important raw materials of amino acid transfusion.

    L-Proline has been used universally as food additive, catalyst and raw materials of fine chemical industry.

    Functions: Proline and its derivatives are often used as asymmetric catalysts in proline organocatalysis reactions. The CBS reduction

    and proline catalysed aldol condensation are prominent examples.In brewing, proteins rich in proline combine with polyphenols to

    produce haze (turbidity). L-Proline is an osmoprotectant and therefore is used in many pharmaceutical, biotechnological applications.

    The growth medium used in plant tissue culture may be supplemented with proline. This can increase growth, perhaps because it

    helps the plant tolerate the stresses of tissue culture.

    1.Used as amino acid injection, compound amino acid infusion, food additives, nutritional supplements, fluid.

    2.Used as biochemical research, medicine for malnutrition, protein deficiency, gastrointestinal disease, burns, and postoperative

    protein supplement.

    3.Used as nutritional supplements. Flavors with sugar fever occurs amino - carbonyl reaction, can generate a special flavor substances.

    China GB 2760-86 provides can be used as a spice.

    4.Used as Amino acid drugs. One of the raw materials of compound amino acid transfusion for malnutrition, protein deficiency,

    a protein supplement after severe gastrointestinal disease, burns and surgery.

    5.Used as Pharmaceutical raw materials and food additives.
