Tyrosine (luv luv li Tyr lossis Y) lossis 4 - Hydroxyphenylalanine, yog ib ntawm 22 cov amino acids uas tau siv los ntawm cov tshuaj muaj proteins. Nws codonsare ubac thiab UAU. Nws yog qhov tsis - Qhov tseem ceeb amino acid nrog ib pawg sab nrauv. Lo lus "Tyrosine" yog los ntawm Greek Tyros, lub ntsiab lus cheese, raws li nws tau tshawb pom hauv 1846 los ntawm German Chemist Judeus von LieBig hauv cov proteinasein los ntawm cheese. Nws yog hu ua tyrosyl thaum hu ua kev ua haujlwm muaj pab pawg saw.yROrotransmitting qib (tshwj xeeb dopam thiab norepinephrine) tab sis harlitrate yog tias muaj kev cuam tshuam rau kev xav. Cov nyhuv ntawm lub siab yog pom ntau ntxiv hauv tib neeg raug rau cov kev ntxhov siab.
Ib cag ntawm ua proteinogenic aminoacid, Tyrosine muaj lub luag haujlwm tshwj xeeb los ntawm kev tsim txiaj ntawm phenol ua haujlwm. IToccurs nyob rau hauv cov protein uas yog ib feem ntawm cov teeb liab transductions. Nws ua haujlwm tau txais cov neeg tau txais cov pab pawg phosphate uas tau hloov pauv los ntawm txoj kev muaj proteinkinases (yog li hu ua releptor tyrosine kinases). Phosphorherlation ntawm hydroxylgroup hloov cov kev ua ntawm cov hom phiaj protein.
Ib qho chaw seem tyrosine kuj ua lub luag haujlwm tseem ceeb hauv photosynthesis. Hauv cov chloroplasts (Pharsystem II), nws ua raws li tus neeg pub ua tus neeg ua haujlwm hauv qhov txo qis ntawm oxidized chlorophyllized chlorophyll. Hauv cov txheej txheem no, nws undergoes depeproation ntawm nws cov phenolic huag - Pawg. Qhov no radical yog tom qab nyob rau hauv cov photicsem ii los ntawm plaub tus tub ntxhais hluas manganese clusters.
Ib tug xov tooj ntawm cov kev tshawb fawb tau pom Tyrosine Tyrosine Tyrosine Tyrosine Tyrosine Tyrosine Kev ntxhov siab, kev ua haujlwm hnyav, nrog rau kev sib sau ua ke ntawm kev tuag lossis kev ua kom muaj kev ntxhov siab thiab kev ua tau zoo hauv kev nkag siab thiab lub cev ua haujlwm pom hauv kev ua neeg vwm; Txawm li cas los xij, vim Tyrosine hydroxylase yog tus nqi - Lim enzyme, cov teebmeem yog qhov tsis tshua muaj qhov tseem ceeb tshaj li cov l - dopa.
Tyrosine tsis zoo li muaj cov txiaj ntsig tseem ceeb rau kev xav, kev txawj ntse lossis lub cev ua tau zoo hauv qhov xwm txheej ib txwm muaj. Cov tshuaj kuaj txhua hnub txhawb nqa cov ntaub ntawv kuaj mob yog li 100 mg / kg rau ib tus neeg laus, uas muaj txog li 6.8 grams at150 lbs. Cov nyiaj li cas rau 50000 mg ib hnub (koob tshuaj tiv thaiv los ntawm cov neeg tsim khoom lag luam feem ntau; feem ntau yog sib npaug rau 1-3 tsiav tshuaj ntawm tyrosine ntshiab). Nws tsis pom zoo kom tshaj 12000 mg (12 g) ib hnub.

Kev tsim kho tshiab, zoo zoo thiab ntseeg tau yog cov tseem ceeb ntawm peb cov lag luam. Cov ntsiab cai no niaj hnub no puas tau muaj lub hauv paus ntawm peb txoj kev vam meej yog ib nrab hnub nyoog nruab nrab L - tyrosine - 60 - 18 - 4 - colorkem, cov khoom yuav muab rau thoob plaws lub ntiaj teb, xws li: Argentina, Seattle, peb lub tuam txhab muaj ntau lub zog thiab zoo kawg nkaus muag network. Peb xav tias peb tuaj yeem tsim cov lag luam kev sib raug zoo nrog txhua tus neeg muas zaub hauv tsev thiab txawv txav ntawm kev sib nrig sib pab.
