What is l-proline?

L-proline is an amino acid, one of the twenty DNA-encoded amino acids. Its codons are CCU, CCC, CCA, and CCG. It is not an essential amino acid, which means that the human body can synthesize it. It is unique among the 20 protein-forming amino acids in that the amine nitrogen is bound to not one but two alkyl groups, thus making it a secondary amine. The more common L form has S stereochemistry.

 

Application of l-proline benzyl ester hydrochloride:
L-proline benzyl ester hydrochloride and its derivatives are often used as asymmetric catalysts in organic reactions. The CBS reduction and proline catalysed aldol condensation are prominent examples.

L-proline is an osmoprotectant and therefore is used in many pharmaceutical, biotechnological applications.

In brewing, proteins rich in proline combine with polyphenols to produce haze.

L-proline is one of the 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.
