L-(-)-페닐알라닌 C화학적 특성, 용도, 생산
화학적 성질
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.출처
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.용도
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.정의
ChEBI: The L-enantiomer of phenylalanine.제조 방법
From PTS-negative Escherichia coli bioengineered strains.일반 설명
Odorless white crystalline powder. Slightly bitter taste. pH (1% aqueous solution) 5.4 to 6.공기와 물의 반응
Water soluble. Aqueous solutions are weak acids.반응 프로필
L-Phenylalanine may be light sensitive. Act as weak acids in solution.건강위험
ACUTE/CHRONIC HAZARDS: When heated to decomposition L-Phenylalanine emits toxic fumes of nitrogen oxides.화재위험
Flash point data for L-Phenylalanine are not available; however, L-Phenylalanine is probably combustible.Safety Profile
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.Purification Methods
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.
