L-Proline CAS:147-85-3 Introduction:
L - proline (proline) is one of 18 kinds of amino acids the human body protein synthesis, room temperature is colorless to white crystal or crystalline powder, slight odor, taste sweet, soluble in water and ethanol, insoluble in ether and isopropyl alcohol and butanol, soluble in mineral acids.Amino acid is a general term for a class of organic compounds containing amino and carboxyl, the existence of the amino acids in the human body, not only provides the important raw material for protein synthesis, and to promote growth, normal metabolism and provides a material basis to sustain life.

L-Proline CAS:147-85-3 Function:
1.H&Z® L-Proline  is used as amino acid injection, compound amino acid infusion, food additives, nutritional supplements, fluid
2.L-Proline  is used as biochemical research, medicine for malnutrition, protein deficiency, gastrointestinal disease, burns, and postoperative protein supplement.
3.L-Proline  is 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.
