Chemische Eigenschaften

White crystalline powder

Chemische Eigenschaften

L-Phenylalanine has no odor and a slight bitter taste. It melts with decomposition at about 283°C. The pH of a 1 in 100 solution is between 5.4 and 6.0. FEMA notes this chemical is used in cocoa substitute only.

Occurrence

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

phenylalanine is a conditioning agent with greater application in hair care than in skin care preparations. It is also used in suntan products.

Verwenden

L-Phenylalanine 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 conv erted into dopamine, norepinephrine, and epinephrine. L-Phenylalanine is produced for medical, feed, and nutritional applications such as in the preparation of Aspartame.

Verwenden

L-phenylalanine is an amino acid used as a skin-conditioning agent. It has greater use in hair care than in skin care products.

Definition

ChEBI: The L-enantiomer of phenylalanine.

synthetische

From PTS-negative Escherichia coli bioengineered strains.

Allgemeine Beschreibung

Odorless white crystalline powder. Slightly bitter taste. pH (1% aqueous solution) 5.4 to 6.

Air & Water Reaktionen

Water soluble. Aqueous solutions are weak acids.

Reaktivität anzeigen

L-Phenylalanine may be light sensitive. Act as weak acids in solution.

Health Hazard

ACUTE/CHRONIC HAZARDS: When heated to decomposition L-Phenylalanine emits toxic fumes of nitrogen oxides.

Brandgefahr

Flash point data for L-Phenylalanine are not available; however, L-Phenylalanine is probably combustible.

Sicherheitsprofil

Mildly toxic by intraperitoneal route. An experimental teratogen. Experimental reproductive effects. Human mutation data reported. When heated to decomposition it emits toxic fumes of NOx.

läuterung methode

Likely impurities are leucine, valine, methionine and tyrosine. Crystallise L-phenylalanine from water by adding 4volumes of EtOH. Dry it in vacuo over P2O5. Also crystallise it from saturated refluxing aqueous solutions at neutral pH, or 1:1 (v/v) EtOH/water solution, or conc HCl. It sublimes at 176-184o/0.3mm with 98.7% recovery and unracemised [Gross & Gradsky J Am Chem Soc 77 1678 1955]. [Greenstein & Winitz The Chemistry of the Amino Acids J. Wiley, Vol 3 pp 2156-2175 1961, Beilstein 14 IV 1552.]
