L-Proline by MP Biomedicals is a high purity reagent. This amino acid contains an -amino group, an -carboxylic acid, and a side chain pyrrolidine, classifying it as a non-polar (at physiological pH), aliphatic amino acid. This preparation is available as a white powder which is soluble in alcohol and water, however it is insoluble in ether, butanol isopropanol. It is classified as non-essential in humans, since the body can synthesize it from the non-essential amino acid L-glutamate. Proline is the only proteinogenic amino acid with a secondary amine. CAS No. 147-85-3 Quantity Provided: 100 gm per pack Molecular Formula: C5H9NO2 Molecular Weight: 115.13 Soluble in water L-Proline is widely used in chemical and biological sectors. Proline and its derivatives are frequently used as asymmetric catalysts in proline organocatalysis reactions. The CBS reduction and proline catalysed aldol condensation are examples of this. It has been used as a supplement during the preparation of chondrogenic medium and synthetic dextrose minimal medium (SD). It is also used as a standard during the identification of metabolites in serum samples. L-Proline is used in a study to prepare L-proline-L-phenylalanine (L-Pro-L-Phe) mixture in aqueous acetonitrile. L-Proline is used as an osmoprotectant in many pharmaceutical, biotechnological applications.
