化學(xué)的特性
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.
天然物の起源
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.
使用
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.
製造方法
By microbial bioengineered process.
定義
ChEBI: An aromatic amino acid that is alanine in which one of the methyl hydrogens is substituted by a phenyl group.
一般的な説明
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.
副作用
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.
純化方法
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].
