Chemische Eigenschaften
DL-Phenylalanine has a sweet taste. It is an essential amino acid that plays a key role in the biosynthesis of other amino acids and some neurotransmitters.
Occurrence
Phenylalanine is the most commonly found aromatic amino acid in proteins and enzymes with a molar ratio of 3.5% compared to the other amino acids, about double the amount of any other aromatic amino acid. Reported found in white bread, macaroni, egg noodles, corn flakes, corn grits, oatmeal, wheat bran, wheat flakes, shredded wheat, barley, brown rice, rye flour, whole grain wheat flour, buttermilk, blue cheese, cheddar cheese, cottage cheese, cream cheese, parmesan cheese, bacon, cured ham, frankfurters, pork sausage, canned red kidney beans, canned sweet corn, canned peas, canned lima beans, canned potatoes, canned asparagus, canned snap beans, canned beets, beef, lamb, fresh ham, veal round, beef liver, chicken, chicken liver, turkey and other natural sources.
Verwenden
DL-Phenylalanine is used to?relieve cases of minor depression?and other mood issues as well as and physical discomforts and pain. It is also used in acupuncture?anesthesia, alcohol withdrawal.
Verwenden
DL-Phenylalanine may be used in the synthesis of ternary piroxicam (Pir; 4-hydroxy-2-methyl-N-(2-pyridyl)-2H-1,2-benzothiazine-3-carboxamide 1,1-dioxide) complexes of Fe(II), Fe(III), Co(II), Ni(II), Cu(II) and Zn(II).
Verwenden
Component of the artificial sweetner aspartame, q.v.; nutrient.
Definition
ChEBI: An aromatic amino acid that is alanine in which one of the methyl hydrogens is substituted by a phenyl group.
synthetische
By microbial bioengineered process.
Allgemeine Beschreibung
Phenylalanine is an amino acid. It participates in the preparation of ternary piroxicam complexes of Fe(II), Fe(III), Co(II), Ni(II), Cu(II) and Zn(II). Characterization of these complexes by elemental analyses, molar conductance, IR, UV-Vis, magnetic moment, diffuse reflectance and X-ray powder diffraction methods has been conducted. Crystalline DL-phenylalanine was prepared by its reduction in silica gel by solubility method.
Nebenwirkungen
When taken by mouth: L-phenylalanine is commonly consumed in foods. L-phenylalanine, D-phenylalanine, and DL-phenylalanine are possibly safe when used as medicine, short-term. Side effects might include anxiety, headache, and constipation. When applied to the skin: Phenylalanine cream is possibly safe when used in the short-term.
läuterung methode
dl-Phenylalanine crystallises from H2O or H2O/EtOH in large plates and is dried under vacuum over P2O5. S-Phenylalanine ethyl ester hydrochloride has m 156-158o and [ ] D -7.8o (c 2, H2O) after crystallisation from EtOH/Et2O [Billimoria & Cook J Chem Soc 2328 1949, Beilstein 14 IV 1556]. [Greenstein & Winitz The Chemistry of the Amino Acids J. Wiley, Vol 3 pp 2156-2175 1961, Beilstein 14 III 1229, 14 IV 1553.]
