Properties: The orthorhombic crystal system is anhydrous, and the monoclinic system contains 1 molecule of crystal water; odorless and has a strong sweet taste; the melting point is 200°C (decomposition); the impurities are hygroscopic; because it is sub- Amino acids have different properties from other amino acids; they are easily soluble in water (154.56g/100ml.20℃) and ethanol, but insoluble in isopropyl alcohol.
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 Pharmaceutical and other industries.
Usage: Nutritional supplement, flavoring agent. When heated with sugar, an amino acid-carbonyl reaction occurs, which can generate special flavor substances.

application
1. Used in amino acid injections, compound amino acid infusions, food additives, nutritional supplements, etc.
2. Used in biochemical research and medicinally for malnutrition, protein deficiency, gastrointestinal diseases, burns, and postoperative protein supplementation.
3. Nutritional supplements. Flavoring agents react with sugar when heated to produce amino-carbonyl groups, which can produce special flavor substances. It can be used as a spice according to my country's GB 2760-86.
4. Amino acid drugs. It is one of the raw materials for compound amino acid infusion and is used for protein supplementation after malnutrition, protein deficiency, severe gastrointestinal diseases, burns, and surgical operations.
5. Pharmaceutical raw materials and food additives.
