Product Detail

Khoom cim npe

l-tyrosine

piav qhia luv luv

Tyrosine (abbreviated li Tyr los yog Y) los yog 4-hydroxyphenylalanine yog ib qho ntawm 22 amino acids siv los ntawm cov hlwb los tsim cov proteins.Nws tuaj yeem siv los tsim cov proteins hauv hlwb, nrog cov codons UAC thiab UAU.Nws yog ib qho tsis tseem ceeb amino acid uas muaj cov pawg polar sab thiab tuaj yeem tsim los ntawm tib neeg lub cev.Lo lus 'tyrosine' los ntawm Greek tyros, txhais tau tias cheese.Nyob rau hauv lub xyoo pua puv 19, nws tau pom thawj zaug los ntawm German chemist Eustus von Libich hauv casein cheese, thiab thaum siv los ua ib pawg ua haujlwm lossis sab, nws hu ua tyrosine.

muaj nuj nqi

Ntxiv rau qhov ua cov protein amino acid, tyrosine plays lub luag haujlwm tshwj xeeb hauv cov teeb liab hloov pauv hauv cov protein los ntawm kev cia siab rau phenolic ua haujlwm pab pawg.Nws muaj nuj nqi yog raws li ib tug receptor rau phosphate pawg pauv los ntawm cov protein kinases (hu ua tyrosine kinase receptors), thaum lub phosphorylation ntawm hydroxyl pawg hloov cov kev ua ntawm lub hom phiaj protein.

Tyrosine kuj tseem ua lub luag haujlwm tseem ceeb hauv photosynthesis, ua tus kws kho hluav taws xob hauv kev txo cov tshuaj tiv thaiv oxidized chlorophyll hauv chloroplasts (Photosystem II), deprotonation ntawm phenolic OH pawg, thiab thaum kawg txo los ntawm plaub pawg manganese pawg hauv Photosystem II.

Qhov chaw noj zaub mov

Tyrosine tuaj yeem tsim los ntawm phenylalanine hauv lub cev thiab tuaj yeem pom muaj ntau yam khoom noj muaj protein ntau xws li nqaij qaib, qaib ntxhw, ntses, mis nyuj, yogurt, cheese, cheese, txiv laum huab xeeb, almonds, taub taub, noob hnav, taum, taum lima, avocados, thiab txiv tsawb.

L-tyrosine yog ib qho tsis tseem ceeb amino acid thiab ib qho ntawm cov khoom tseem ceeb hauv txoj kev methionine metabolism.Nws yog dav nyob rau hauv cov kab mob thiab ua lub luag haujlwm tseem ceeb hauv ntau yam txheej txheem lom neeg.

L-tyrosine yog ib feem ntawm cov proteins thiab koom nrog cov txheej txheem synthesis ntawm cov protein.Nws kuj yog ib qho ua ntej ntawm ntau yam bioactive tshuaj, suav nrog catecholamine neurotransmitters xws li dopamine, norepinephrine, thiab adrenaline, nrog rau cov thyroid hormones thiab melanin.

Tsis tas li ntawd, L-tyrosine tseem koom nrog hauv kev sib txuas ntawm cov khoom siv roj ntsha tseem ceeb los ntawm cov enzymes hauv lub cev, xws li tyrosine kinase thiab tyrosine hydroxylase, uas koom nrog hauv kinase signaling pathways thiab physiological regulation.

Kev noj L-tyrosine tuaj yeem tau txais los ntawm kev noj zaub mov, nrog rau cov khoom noj muaj ntau xws li txiv ntoo, noob, nqaij, ntses, thiab khoom noj siv mis.Tsis tas li ntawd, L-tyrosine tuaj yeem hloov pauv los ntawm lwm cov amino acid, phenylalanine, los ntawm txoj kev tyrosine synthesis hauv lub cev.
