Daim ntawv thov ntawm L-phenylalanine yog dab tsi?
Phenylalanine, uas yog D, L- -amino -phenylpropionic acid, yog ib tug dawb los yog tsis muaj xim flake crystal, nrog ib tug saj ntawm iab almond, soluble nyob rau hauv dej, me ntsis soluble nyob rau hauv cawv, insoluble nyob rau hauv diethyl ether, melting point 283 degree. Nws tau pom thawj zaug thiab cais tawm ntawm lupine seedlings los ntawm Schulze nyob rau hauv 1879. Tom qab ntawd Fischer cais cov tsiaj protein zoo nyob rau hauv thaum ntxov 20th caug xyoo. Tam sim no, phenylalanine tuaj yeem siv tau ntau lawm.
1.Hauv kev lag luam khoom noj khoom haus, L-phenylalanine thiab L-aspartic acid condensation form aspartame (APM), vim nws cov qab zib (200 npaug ntawm sucrose), qis calorific nqi, yooj yim metabolism thiab lwm yam zoo, heev haum rau cov neeg mob rog rog thiab diabetics. siv;
2.Nws tau siv dav hauv cov khoom noj khoom haus thiab kev ua haujlwm, ntawm cov L-phenylalanine thiab lwm yam khoom noj muaj zog ua haujlwm los ntawm ntau cov amino acids tuaj yeem siv los ua zaub mov noj rau cov neeg tsav nkoj, cov neeg caij nkoj, cov nkoj hauv nkoj thiab cov neeg dhia dej tob.
3.L-phenylalanine yog siv rau hauv cov zaub mov ci, ntawm ib sab, nws ntxiv dag zog rau cov amino acids, tab sis kuj tuaj yeem ua rau cov suab thaj, Maillard cov tshuaj tiv thaiv, txhim kho cov zaub mov tsw. Hershey tau pom tias qhov sib ntxiv ntawm phenylalanine, leucine thiab degraded qab zib rau unbaked cocoa tuaj yeem txhim kho qhov tsw ntawm cocoa thaum ua tiav.
4.Hauv kev lag luam kws tshuaj, nws yog ib qho tseem ceeb ntawm cov khoom siv tshuaj infusion, lossis cov khoom siv hluavtaws lossis cov khoom siv zoo ntawm qee cov tshuaj, xws li HIV protease inhibitors, p-fluorophenphenylalanine, alanine mustard, formyl lysosarcoma, hlwb neurotransmitter thiab lwm yam khoom siv raw. cov ntaub ntawv;
5.Thaum siv los ua tus nqa khoom, nws tuaj yeem thauj cov tshuaj antitumor mus rau hauv qhov chaw qog, uas tuaj yeem tsis tsuas yog inhibit qog kev loj hlob, tab sis kuj txo cov tshuaj toxicity ntawm cov qog. Tsis tas li ntawd, nws tseem tuaj yeem siv los npaj cov kab lis kev cai kho mob.
Tau kawg, daim ntawv thov teb ntawm L-phenylalanine tseem tab tom tsim. Piv txwv li, Monsanto Tuam Txhab tau tsim cov thev naus laus zis ntawm kev sib txuas chiral intermediates los ntawm L-phenylalanine thiab nws cov derivatives.
