출처Phenylalanine 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.
용도DL-Phenylalanine is used torelieve cases of minor depressionand other mood issues as well as and physical discomforts and pain. It is also used in acupunctureanesthesia, alcohol withdrawal.
일반 설명Phenylalanine 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.
By microbial bioengineered process.

순도시험(1) 납 : 이 품목 5.0g을 취하여 원자흡광광도법 또는 유도결합라즈마발광광도법에 따라 시험할 때, 그 양은 5.0ppm 이하이어야 한다.
확인시험(1) 이 품목의 수용액(1→1,000) 5mL에 닌히드린시액 1mL를 가하여 가열하면 자색을 나타낸다. (2) 이 품목의 수용액(1→100) 5mL에 중크롬산칼륨시액 몇 방울을 가하여 가열하면 특유한 냄새가 난다. (3) 이 품목 10mg에 질산칼륨 0.5g 및 황산 2mL를 가하여 수욕상에서 20분간 가열한 다음 식히고 히드록실아민시액 2mL를 가하여 얼음물 중에 10분간 방치한 다음 즉시 수산화나트륨시액 10mL를 가하여 방치하면 자색을 나타낸다.
정량법이 품목을 105℃에서 2시간 미리 건조한 다음 약 0.5g을 정밀히 달아 빙초산(비수적정용) 70mL를 가하여 녹이고 0.1N 과염소산용액으로 적정한다(지시약 : 크리스탈바이올렛․빙초산시액 2방울). 종말점은 액의 자색이 청색을 지나 녹색으로 변하는 점이다. 따로 같은 방법으로 공시험을 한다.0.1N 과염소산용액 1mL = 16.52mg C9H11NO2
