Wholesale D-Phenylalanine Chinese Supplier Food Grade FDA Approved Health Care Product

The scientific name of phenylalanine is α-amino-β-phenylpropionic acid. It is a kind of α-amino acid. It has L type, D type and racemic DL type. The L type is one of the essential amino acids for human body. Phenylalanine was first discovered by Schulze and Barbieri in the late 1880s, a new amino acid isolated from lupine seedlings, and an empirical chemical formula was proposed as C9H11NO2. Erlemeyer and Lipp successfully synthesized phenylalanine through chemical synthesis for the first time in 1882, but their spatial configuration was not explored. Then Fischer accidentally isolated phenylalanine when hydrolyzing casein with hydrochloric acid in 1901. Since then, people have further studied phenylalanine. D-phenylalanine is a kind of α-amino acid. Its physical state is white powder or white crystalline solid at room temperature. Its melting point is 283°C. Its isoelectric point (25°C) is 5.48. Its solubility in water at 25°C is 27g/L. Slightly soluble in methanol, ethanol, insoluble in ether, etc., specific optical rotation [α]25D=+34.5 (c=1.0, H2O). Like other D-amino acids, D-phenylalanine is a very important chiral intermediate in organic synthesis, new drug development, and the synthesis of peptide compounds, and because of the special structure and activity of D-phenylalanine itself Sex is getting more and more attention from people.
