Indications and Usage
Proline (abbreviated
as Pro or P) is an α-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 *0 protein-forming amino
acids in that the α-amino group is secondary.
Proline 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 (turbidity).
