CAS 17942-32-4: L-phenylalanine-alpha,beta,beta,2,3,4,5

Applications L-Phenyl-d5-alanine-2,3,3-d3 is an isotope labelled compound of L-Phenylalanine (P319415). L-Phenylalanine (Aspartame EP Impurity C) is an essential amino acid. L-Phenylalanine is biologically converted into L-tyrosine, another one of the DNA-encoded amino acids, which in turn is converted to L-DOPA and further converted into dopamine, norepinephrine, and epinephrine. L-Phenylalanine is produced for medical, feed, and nutritional applications such as in the preparation of Aspartame. Neuroprotective product. References Hollunger, G. et al.: Acta Pharmacol.

L-Phenyl-d5-alanine-2,3,3-d3 is a molecule that has been studied in micelles. The orientation of the molecule can be analyzed by multinuclear NMR spectroscopy. Lamellar phases are formed when L-phenylalanine is mixed with water and few other solutes, such as sodium chloride. These phases are characterized by small droplets or cylinders of water surrounded by a bilayer of surfactant molecules. The interaction of L-phenylalanine with the surfactant molecules is analyzed using techniques such as infrared spectroscopy and X-ray diffraction.
