What is L-Proline USP

Proline is one of the 20 proteinogenic amino acids, 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 (turbidity).
