Product Description

L-proline (proline for short) is one of the 18 amino acids synthesized by the human body. It is colorless to white crystal or crystalline powder at room temperature, slightly smelly, slightly sweet, easily soluble in water, insoluble in ethanol, insoluble in ether . Amino acids are a general term for a class of organic compounds containing amino and carboxyl groups. The existence of amino acids in the human body not only provides an important raw material for the synthesis of proteins, but also provides a material basis for promoting growth, carrying out normal metabolism and maintaining life.

 

 

 

 

1. Used in biochemical research, medicine for malnutrition, protein deficiency, gastrointestinal diseases, burns and postoperative protein supplement.
2. Nutritional supplements. Flavor agent, co-heated with sugar, amino - carbonyl reaction, can produce special flavor substances. According to GB 2760-86, it can be used as a spice.
3. Used for amino acid injection, complex amino acid infusion, food additives, nutrition replenishment liquid, etc.
4. Pharmaceutical raw materials and food additives.
5. Proline itself is chiral, so it is commonly used as a chiral lead reagent in the total synthesis of some natural products;
At the same time, as an optically active adjuvant, proline plays an important role in asymmetric total synthesis
[1]. Asymmetric catalysis When proline is used as the chiral catalyst, the carbonyl compound can undergo asymmetric Michael reaction, and the product is β-hydroxyaldehyde (or ketone) (Formula 1)
[2]. Under the catalysis of L-proline, the nitroso compound can undergo α-amine oxidation with the carbonyl compound (Equation 2)
[3]. L-proline can also catalyze asymmetric Diels-Alder reactions (Equation 3)
