Qhov sib txawv tseem ceeb ntawm lysine thiab leucine yog tias lysine yog aliphatic alpha amino acid, whereas leucine yog branched alpha amino acid.
Lysine thiab leucine yog alpha amino acid molecules uas tseem ceeb rau peb lub cev. Ib qho alpha-amino acid yog ib qho amino acid molecule uas muaj cov amino pawg, pawg carboxylic acid thiab ib sab saw ntawm hydrocarbon units.
Lysine yog dab tsi?
Lysine yog ib qho alpha amino acid molecule uas muaj txiaj ntsig zoo hauv cov protein biosynthesis. Peb tuaj yeem sau lub npe amino acid no li Lys lossis K. Cov amino acid no muaj cov alpha amino pawg, pawg alpha carboxylic acid, thiab ib sab saw lysyl. Cov saw lysyl ua rau cov amino acid no yog ib qho yooj yim compound. Nws kuj ua rau lysine them thiab aliphatic amino acid. Cov codons uas encode rau lysine amino acid yog AAA thiab AAG. Lub alpha carbon atom ntawm no molecule yog chiral, thiab nws tshwm sim raws li ib tug racemic sib tov ntawm nws enantiomers (L thiab D enantiomers).
Daim duab 01: Cov Qauv Tshuaj ntawm Lysine
Peb lub cev tsis tuaj yeem tsim cov lysine molecules. Tab sis nws yog ib qho tseem ceeb ntawm tib neeg. Yog li ntawd, peb yuav tsum tau txais nws los ntawm cov khoom noj. Txawm li cas los xij, muaj qee yam kab mob uas tuaj yeem tsim cov lysine los ntawm ob txoj hauv kev biosynthetic: diaminopimelate txoj kev thiab alpha aminoadipate txoj kev. Ntxiv mus, catabolism ntawm lysine tshwm sim los ntawm txoj kev saccharopine.
Muaj ntau lub luag haujlwm ntawm lysine hauv tib neeg lub cev, suav nrog cov proteinogenesis, hla kev sib txuas ntawm collagen polypeptides, kev noj cov zaub mov tseem ceeb hauv cov zaub mov, hauv kev tsim cov carnitine, thiab lwm yam. Tsis tas li ntawd, nws feem ntau koom nrog kev hloov kho histone thiab cuam tshuam rau lub cev. epigenome.
Vim nws yog ib qho tseem ceeb amino acid, qhov tsis muaj lysine hauv peb lub cev tuaj yeem ua rau ntau yam kab mob, suav nrog cov ntaub so ntswg tsis zoo, cov metabolism hauv fatty acid tsis zoo, anemia, thiab lub cev tsis muaj zog protein ntau.
Leucine yog dab tsi?
Leucine yog ib qho amino acid uas muaj txiaj ntsig zoo hauv biosynthesis ntawm cov protein. Peb tuaj yeem sau nws lub npe ua Leu lossis L. Nws yog ib qho tseem ceeb alpha amino acid vim tias nws muaj alpha amino acid pawg, ib pawg alpha carboxylic acid, thiab ib sab saw isobutyl pawg uas ua rau nws yog nonpolar aliphatic amino acid. Ntxiv mus, qhov no yog ib qho tseem ceeb amino acid nyob rau hauv tib neeg, thiab peb lub cev tsis tuaj yeem tsim nws. Yog li ntawd, peb yuav tsum coj nws los ntawm kev noj haus. Nqaij, khoom noj siv mis, kua proteins thiab taum mas muaj leucine. Cov codons uas encode leucine muaj xws li UUA, UUG, CUU, CUC, CUA, thiab CUG.
Daim duab 02: Cov Qauv Tshuaj ntawm Leucine
Cov amino acid no muaj txiaj ntsig zoo li cov khoom noj ntxiv uas nws muaj tus lej E E641. Peb tuaj yeem faib nws raws li kev ua kom tsw qab. Nyob rau hauv cov ntaub ntawv ntawm kev noj haus ntxiv, leucine tuaj yeem ua rau qeeb qeeb ntawm cov leeg nqaij los ntawm kev ua kom cov leeg nqaij protein ntau hauv cov nas hnub nyoog, raws li qee qhov kev tshawb fawb tshawb fawb. Tab sis kev noj qab haus huv ntev ntawm leucine tsis tau nce cov leeg nqaij lossis lub zog hauv cov txiv neej laus noj qab haus huv.
Dab tsi yog qhov zoo sib xws ntawm Lysine thiab Leucine?
- Lysine thiab leucine yog alpha amino acids.
- Ob leeg yog qhov tseem ceeb rau peb lub cev.
- Cov amino acids no tsis yog tsim los hauv peb lub cev; peb yuav tsum coj lawv los ntawm peb cov khoom noj.
Qhov txawv ntawm Lysine thiab Leucine yog dab tsi?
Lysine thiab leucine yog alpha amino acid molecules uas tseem ceeb rau peb lub cev. Qhov sib txawv tseem ceeb ntawm lysine thiab leucine yog tias lysine yog ib qho aliphatic alpha amino acid whereas leucine yog ib tug branched alpha amino acid.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm lysine thiab leucine.
Summary – Lysine vs Leucine
Lysine thiab leucine yog alpha amino acid molecules uas tseem ceeb rau peb lub cev. Hauv lwm lo lus, cov amino acids no muaj cov qauv tshuaj zoo sib xws ntawm lub hauv paus carbon atom uas muaj cov pab pawg amine, pawg carboxylic acid thiab ib sab saw ntawm hydrocarbon units txuas rau hauv nruab nrab carbon. Qhov sib txawv tseem ceeb ntawm lysine thiab leucine yog tias lysine yog aliphatic alpha amino acid, whereas leucine yog ib ceg alpha amino acid.
