WebJan 24, 2024 · Proline was the second amino acid synthesized before its presence as a product of the hydrolysis of the protein molecule was established. Willstatter, investigating the position of the carboxyl group in N-methylproline, first obtained this amino acid in 1900. WebOsmoregulation in plants under low water potential relies on synthesis and accumulation of osmoprotectants or osmolytes such as soluble proteins, sugars, and sugar alcohols, quaternary ammonium compounds, and amino acids, like proline. This review highlights the role of osmolytes in water-stressed plants and of enzymes entailed in their metabolism.
