Description

Proline (abbreviated as Pro or P) is an alpha-amino acid or more technically an iminio acid. The L-isomer is one of the 22 proteinogenic amino acids, i.e., the building blocks of proteins. It is classified as a polar amino acid, because of the hydrophilic nature of its cycloalkyl side chain. It is unique among the 20 protein-forming amino acids in that the alpha-amino group is secondary. The distinctive cyclic structure of proline's side chain locks its φ backbone dihedral angle at approximately −75°, giving proline an exceptional conformational rigidity compared to other amino acids. Proline is biosynthetically derived from the amino acid L-glutamate and its immediate precursor is the imino acid (S)-1-pyrroline-5-carboxylate (P5C). Enzymes involved in a typical biosynthesis include: Glutamate kinase; Glutamate dehydrogenase and Pyrroline-5-carboxylate reductase. Proline and its derivatives are often used as asymmetric catalysts in organic 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). Proline is typically the most abundant amino acid found in wine. During fermentation of wine most of the amino acids are practically depleted from the grape juice/ grape must (the juice component including skins, seeds and stems) by the time the first 30 g of sugar have been fermented. Yeast make use of alanine and argnine acids and ammonium (slightly) after the depletion of the other amino acids. Yeast then assimilate arginine only after the disappearance of ammonium from the grape must/juice. Yeasts do not utilize proline during fermentation although it is one of the principle amino acids found in must. During fermentation, yeasts assimilate between 1 and 2 g/L of amino acids. Towards the end of fermentation, yeasts excrete significant but variable amounts of different amino acids. Finally at the end of alcoholic fermentation, a few hundred mg/L of amino acids remain with proline generally represents half.
