Insoluble in ether, butanol and isopropanol, soluble in mineral acids. Amino acid is a general term for a class of organic compounds containing amino and carboxyl groups. The presence of amino acids in the human body not only provides important raw materials for protein synthesis, but also provides a material basis for promoting growth, normal metabolism, and maintaining life. L-proline is one of the important amino acids for the synthesis of human protein, an important raw material for amino acid infusion, and the main intermediate for the synthesis of first-line antihypertensive drugs such as captopril and enalapril. It has been widely used in food and Pharmaceutical and other industries.
Uses: nutritional supplements, flavoring agents, co-heated with sugar to produce amino acid-carbonyl reaction, can produce special flavor substances.
