Qhov sib txawv tseem ceeb ntawm lysine thiab arginine yog tias lysine yog ib qho tseem ceeb amino acid uas tseem ceeb rau tib neeg, thaum arginine yog ib qho tseem ceeb amino acid uas tsis tseem ceeb rau tib neeg.
Lysine thiab arginine yog qhov zoo them cov amino acids yooj yim. Ob leeg yog hydrophilic amino acids. Feem ntau, cov amino acids tseem ceeb yog polar. Lawv feem ntau muaj nyob rau ntawm qhov chaw ntawm cov protein. Lawv cov pKa qhov tseem ceeb yog siab heev, yog li lawv nyiam khi nrog protons thiab tau txais tus nqi zoo hauv cov txheej txheem. Ob qho amino acids nyob rau hauv qhov chaw ntawm cov protein ua lub luag haujlwm tseem ceeb hauv kev ruaj ntseg ntawm cov protein. Lawv tsim kev sib cuam tshuam ionic thiab hydrogen bonds hauv cov proteins. Lawv kuj cuam tshuam nrog dej molecules.
Lysine yog dab tsi?
Lysine yog ib qho txiaj ntsig zoo ntawm cov amino acid uas tseem ceeb rau tib neeg. Nws muab kev ruaj ntseg tsawg rau cov protein vim nws cov qauv geometric. Cov amino acid no tau pom thawj zaug los ntawm cov protein casein hauv cov mis nyuj los ntawm German biochemist Ferdinand Heinrich Edmund Drechsel hauv xyoo 1889. Nws yog ib qho α-amino acid uas koom nrog hauv cov protein biosynthesis. Nws muaj α-amino pawg, α-carboxylic acid pab pawg, thiab cov lysyl sab saw. Tib neeg lub cev tsis tuaj yeem tsim cov lysine. Yog li, lysine yog ib qho tseem ceeb amino acid. Nws yuav tsum tau muab los ntawm kev noj haus. Txawm li cas los xij, qee cov kab mob tuaj yeem tsim cov lysine los ntawm ob txoj hauv kev biosynthetic hu ua diaminopimelate thiab α-aminoadipate txoj kev. Tab sis txoj hauv kev no xav tau cov enzymes thiab cov substrates uas tsis muaj nyob hauv tib neeg.

Lysine txiaj ntsig
Lysine ua ntau lub luag haujlwm tseem ceeb hauv tib neeg. Lub luag haujlwm tseem ceeb tshaj plaws yog proteinogenesis. Nws pab nyob rau hauv crosslinking ntawm collagen polypeptides thiab uptake ntawm tseem ceeb minerals. Tsis tas li ntawd, nws pab tsim cov carnitine. Tsis tas li ntawd, lysine feem ntau koom nrog hauv kev hloov kho epigenetic histone. Yog li ntawd, nws cuam tshuam rau lub epigenome. Vim nws qhov tseem ceeb hauv cov txheej txheem lom neeg, qhov tsis muaj cov amino acid no tuaj yeem ua rau ntau yam kab mob xws li cov ntaub so ntswg tsis zoo, cov metabolism hauv fatty acid, tsis muaj zog, thiab tsis muaj protein ntau. Nyob rau hauv sib piv, ib tug overabundance ntawm no amino acid ua rau neurological mob.
Arginine yog dab tsi?
Arginine yog ib qho txiaj ntsig zoo ntawm cov amino acid uas tsis tseem ceeb rau tib neeg. Nws muab ntau ruaj khov rau cov protein vim nws cov qauv geometric. Cov amino acid no yog thawj zaug cais tawm los ntawm cov noob qoob loo daj los ntawm German kws tshawb fawb kws tshawb fawb Ernst Schulze thiab nws tus pab cuam Ernst Steiger hauv xyoo 1886. Nws kuj yog ib qho α-amino acid amino acid koom nrog hauv cov protein biosynthesis. Nws muaj α-amino pawg, α-carboxylic acid pawg, thiab ib sab saw uas muaj 3- carbon aliphatic ncaj-chain xaus rau hauv ib pawg guanidino. Nws yog tus precursor rau biosynthesis ntawm nitric oxide.
Daim duab 02: Arginine
Vim tias nws tuaj yeem ua rau tib neeg lub cev, arginine suav tias yog ib qho tseem ceeb lossis tsis tseem ceeb amino acid. Txawm hais tias nws yog ib qho tsis tseem ceeb amino acid, cov me nyuam yug ntxov ntxov tsis tuaj yeem tsim cov arginine sab hauv, ua rau nws cov khoom noj muaj txiaj ntsig zoo rau cov menyuam mos yug ntxov. Cov neeg noj qab haus huv feem ntau tsis xav tau arginine vim nws yog ib feem ntawm tag nrho cov khoom noj muaj protein ntau. Ntxiv mus, tib neeg lub cev tuaj yeem tsim nws los ntawm glutamine ntawm citrulline.
Dab tsi yog qhov zoo sib xws ntawm Lysine thiab Arginine?
- Lysine thiab arginine yog qhov zoo them cov amino acids yooj yim.
- Ob leeg muaj pKa siab.
- Lawv yog polar thiab hydrophilic amino acids.
- Ob leeg yog aliphatic amino acids.
- Lawv tsim kev sib cuam tshuam ionic thiab hydrogen bonds hauv cov proteins.
- Lawv ob leeg pom ntawm cov protein.
Qhov txawv ntawm Lysine thiab Arginine yog dab tsi?
Lysine yog ib qho tseem ceeb ntawm cov amino acid, thaum arginine yog ib qho tseem ceeb tsis tseem ceeb cov amino acid. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm lysine thiab arginine. Tsis tas li ntawd, lysine muab kev ruaj ntseg tsawg rau cov protein vim nws cov qauv geometric, thaum arginine muab kev ruaj ntseg rau cov protein ntau vim nws cov qauv geometric. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm lysine thiab arginine.
Cov hauv qab no infographic teev ntau qhov sib txawv ntawm lysine thiab arginine hauv daim ntawv teev npe rau ib sab ntawm kev sib piv.
Summary – Lysine vs Arginine
Lysine thiab arginine yog ob qho amino acids. Lawv sab saw pawg muaj tag nrho cov nqi zoo ntawm lub cev pH. Lawv tsim ntau yam kev sib tshuam electrostatic hauv cov protein. Yog li, cov amino acids no ua lub luag haujlwm tseem ceeb hauv kev ruaj ntseg protein. Lysine muab kev ruaj ntseg tsawg rau cov protein vim nws cov qauv geometric, tab sis nws yog qhov tseem ceeb rau tib neeg. Hauv qhov sib piv, arginine muab kev ruaj ntseg rau cov protein ntau vim nws cov qauv geometric; Txawm li cas los xij, nws tsis yog qhov tseem ceeb rau tib neeg. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm lysine thiab arginine.
