Qhov sib txawv tseem ceeb ntawm phenylalanine thiab tyrosine yog tias phenylalanine yog ib qho tseem ceeb amino acid uas tsis tuaj yeem tsim hauv peb lub cev thiab yuav tsum tau muab tso rau hauv kev noj haus thaum tyrosine yog ib qho tsis tseem ceeb amino acid uas tuaj yeem tsim los ntawm phenylalanine hauv peb. lub cev.
Muaj nees nkaum amino acids sib txawv. Qee cov amino acids yog cov amino acids tseem ceeb, txhais tau tias lawv tsis tsim nyob rau hauv peb lub cev. Hauv qhov sib piv, muaj qee qhov tsis tseem ceeb amino acids uas tuaj yeem tsim hauv peb lub cev. Phenylalanine yog ib qho tseem ceeb amino acid uas yog ib tug precursor rau tyrosine thaum tyrosine yog ib qho tseem ceeb amino acid. Ob leeg phenylalanine thiab tyrosine yog cov tshuaj tsw qab tsev neeg amino acids. Lawv tseem ceeb heev rau kev tsim cov khoom sib txawv hauv peb lub cev.
YPhenylalanine yog dab tsi?
Phenylalanine yog ib qho tseem ceeb amino acid uas tsis tuaj yeem tsim hauv peb lub cev. Yog li ntawd, nws yuav tsum muaj nyob rau hauv peb cov khoom noj. Mis nyuj, nqaij, nqaij qaib, ntses, tsev cheese, lentils, txiv laum huab xeeb, thiab noob hnav noob hnav yog nplua nuj nyob rau hauv phenylalanine. Phenylalanine yog ib qho precursor rau tyrosine, uas yog ib qho tseem ceeb amino acid. Ntxiv mus, phenylalanine yog ib qho ua ntej rau catecholamines, suav nrog tyramine, dopamine, epinephrine, thiab norepinephrine.
Daim duab 01: Phenylalanine
Structurally, phenylalanine yog ze ze rau dopamine, epinephrine thiab tyrosine. Cov tshuaj formula ntawm phenylalanine yog C9H11NO2thaum lub molecular mass yog 165.19 g / mol. Cov codons UUU thiab UUC hauv mRNA sequence code rau cov amino acid no.
YTyrosine yog dab tsi?
Y Tyrosine yog ib qho tsis tseem ceeb amino acid thiab hydrophobic amino acid. The codons UAC and UAU in mRNA sequence code for tyrosine. Cov tshuaj formula ntawm tyrosine yog C
9H11NO3 thaum molecular mass yog 181.191 g·mol −1 Peb lub cev tuaj yeem tsim cov tyrosine los ntawm phenylalanine. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum muaj qhov pib ntawm phenylalanine txhawm rau tsim tyrosine. Lub enzyme phenylalanine hydroxylase catalyzes hydroxylation ntawm phenylalanine rau hauv tyrosine. Cov enzyme no tau nthuav tawm hauv daim siab thiab lub raum.
Daim duab 02: Tyrosine
Y Tyrosine metabolizes rau hauv cov khoom tseem ceeb hauv peb lub cev xws li epinephrine, norepinephrine, melanin, cov ntaub so ntswg pigments thiab estrogen. Txawm li cas los xij, kev hloov pauv ntawm tyrosine mus rau lwm yam tshuaj yuav tsum muaj folic acid, niacin, vitamin C, thiab tooj liab, thiab lwm yam. Ntxiv mus, tyrosine yog ib qho tshuaj tiv thaiv kab mob amino acid. Yog li ntawd, nws muaj txiaj ntsig zoo rau kev txo qis kev ntxhov siab thiab txhawb zog. Tsis tas li ntawd, tyrosine muaj cov cuab yeej antioxidant. Yog li ntawd, nws muaj txiaj ntsig zoo los tiv thaiv cov cell thiab cov ntaub so ntswg puas los ntawm cov dawb radicals. Tyrosine kuj xav tau rau cov metabolism.
Dab tsi zoo sib xws ntawm Phenylalanine thiab Tyrosine?
- Ob leeg phenylalanine thiab tyrosine yog qhov tseem ceeb amino acids.
- Lawv yog tsev neeg muaj ntxhiab ntawm cov amino acids.
- Phenylalanine hloov mus ua tyrosine los ntawm phenylalanine hydroxylase.
- Ob leeg muaj cov tshuaj tiv thaiv kev nyuaj siab thiab muaj txiaj ntsig zoo hauv kev kho kev nyuaj siab thiab kev ntxhov siab.
- Ob leeg tuaj yeem xa cov teebmeem zoo sib xws.
- Ntxiv mus, lawv muaj txiaj ntsig zoo li cov cim ntawm cov metabolism hauv cov protein.
Qhov txawv ntawm Phenylalanine thiab Tyrosine yog dab tsi?
Phenylalanine yog ib qho tseem ceeb amino acid uas yuav tsum muaj nyob rau hauv peb cov zaub mov thaum tyrosine yog ib qho tseem ceeb amino acid uas yog synthesized los ntawm phenylalanine nyob rau hauv peb lub cev. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm phenylalanine thiab tyrosine. Cov tshuaj formula ntawm phenylalanine yog C9H11NO2 thaum cov tshuaj formula ntawm tyrosine yog C 9H11NO3
Ntxiv mus, codons UUU thiab UUC code rau amino acid phenylalanine thaum codons UAC thiab UAU code rau tyrosine.
Hauv qab no yog qhov sib piv kom ntxaws ntxiv ntawm qhov sib txawv ntawm phenylalanine thiab tyrosine.
Summary – Phenylalanine vs Tyrosine
Phenylalanine yog ib qho tseem ceeb amino acid uas yog tus ua ntej rau tyrosine. Tyrosine yog ib qho tsis tseem ceeb amino acid uas tuaj yeem tsim hauv peb lub cev. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm phenylalanine thiab tyrosine. Raws li txoj cai, lawv muaj kev sib raug zoo thiab ua rau tsev neeg muaj ntxhiab ntawm cov amino acids. Tsis tas li ntawd, lawv tseem ceeb heev rau kev tsim ntau yam sib txuas hauv peb lub cev.
