L-Proline Amino Acid Powder for plant tissue culture and catalyst CAS 63-91-2


L-Proline ( abbreviated as Pro or P; encoded by the codons CCU, CCC, CCA, and CCG ) is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group ( which is in the protonated NH2+ form under biological conditions ), an α-carboxylic acid group ( which is in the deprotonated −COO− form under biological conditions ), and a side chain pyrrolidine, classifying it as a nonpolar ( at physiological pH ), aliphatic amino acid. It is non-essential in humans, meaning the body can synthesize it from the non-essential amino acid L-glutamate.


L-Proline is the only proteinogenic amino acid with a secondary amine, in that the alpha-amino group is attached directly to the side chain, making the α carbon a direct substituent of the side chain.




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.


L-Proline and its derivatives are often used as asymmetric catalysts in proline organocatalysis reactions. The CBS reduction and proline catalysed aldol condensation are prominent examples.

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

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


The growth medium used in plant tissue culture may be supplemented with proline. This can increase growth, perhaps because it helps the plant tolerate the stresses of tissue culture.
