Qhov sib txawv tseem ceeb ntawm beta alanine thiab L alanine yog tias beta alanine yog cov amino acid uas tsis yog-proteinogenic thaum L alanine yog proteinogenic amino acid.
Feem ntau, cov amino acids yog lub tsev tsim cov proteins. Lawv sib xyaw ua ke los tsim cov proteins. Muaj ob pawg ntawm cov amino acids uas tsis yog-proteinogenic thiab proteinogenic. Cov amino acids uas tsis yog-proteinogenic tsis nquag koom nrog rau hauv cov proteins thaum lub sijhawm kev txhais lus. Qee qhov piv txwv ntawm non-proteinogenic amino acids yog GABA, L-DOPA, triiodothyronine, thiab beta alanine. Proteinogenic amino acids, ntawm qhov tod tes, yog cov amino acids uas tau muab tso rau hauv cov proteins thaum txhais lus. Hauv eukaryotes, muaj 21 proteinogenic amino acids. Qee qhov piv txwv ntawm cov proteinogenic amino acids yog histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, L alanine, valine, thiab lwm yam.
Beta Alanine yog dab tsi?
Beta alanine yog cov amino acid uas tsis yog-proteinogenic. Nws yog ib txwm tshwm sim beta amino acid. Hauv beta alanine, cov amino pawg ntawm cov amino acids txuas nrog β carbon ntau dua li cov α carbon ntau dua li niaj zaus. Lub npe IUPAC rau beta alanine yog 3-aminopropanoic acid. Tsis zoo li alpha alanine, beta alanine tsis muaj stereocenter. Lub stereocenter yog ib qho taw tes ntawm ib qho molecule uas muaj cov khoom sib txawv. Kev hloov pauv ntawm ob tus neeg hloov pauv ntawm lub stereocenter ua rau tsim cov stereoisomer.
Daim duab 01: Beta Alanine
Txawm hais tias beta alanine yog ib qho uas tsis yog-proteinogenic amino acid, nws tau hais tias yog tus thawj coj ntawm carnosine peptide los ntawm kev txwv tus nqi. Tsis tas li ntawd, kev nce qib ntawm beta alanine yuav ua rau kom tag nrho cov concentration ntawm carnosine hauv cov leeg. Carnosine txo qhov qaug zog thiab pab txhim kho cov leeg leaner. Cov neeg uas xav tsim lawv cov leeg ib txwm noj hauv beta alanine supplementation kom ntxiv dag zog rau lawv cov beta alanine cia. Raws li kev ntxiv nrog beta alanine nce, carnosine concentration hauv cov leeg thaum kawg ua rau cov leeg nqaij ua haujlwm tawm ntawm kev ua kis las. Tsis tas li ntawd, beta alanine tseem yog ib qho seem ntawm anserine (dipeptide) thiab pantothenic acid (vitamin B 5)..
L Alanine yog dab tsi?
L alanine yog proteinogenic amino acid. L isomer ntawm alanine yog ib qho uas feem ntau muab tso rau hauv cov proteins. L alanine amino acid tsuas yog thib ob rau leucine hauv qhov tshwm sim. Nws tau raug pov thawj tias L alanine tso nyiaj rau 7.8% ntawm cov qauv thawj hauv cov qauv ntawm 1150 proteins. Ntawm qhov tod tes, D alanine tshwm sim hauv cov polypeptides nkaus xwb hauv qee cov kab mob ntawm tes. Nyob rau hauv L alanine, cov amino pawg ntawm cov amino acids yog txuas mus rau ib txwm α carbon. Ntxiv mus, nws kuj muaj stereoisomers.
Daim duab 02: L Alanine
Lub npe IUPAC ntawm L alanine yog 2-aminopropanoic acid. L alanine yog ib qho tsis tseem ceeb amino acid. Nws yog ib txwm tsim enzymatically los ntawm L aspartate siv aspartate β decarboxylase. Nws yog qhov tsawg tshaj plaws ntawm tag nrho cov amino acids. L alanine tau siv los ua ib qho ntxiv hauv cov kab lis kev cai ntawm tes. Tsis tas li ntawd, L alanine yog siv los ua cov khoom noj khoom haus ntxiv, cov khoom xyaw hauv cov tshuaj infusion, thiab ua ntej rau cov khoom siv tshuaj thiab tshuaj
Dab tsi zoo sib xws ntawm Beta Alanine thiab L Alanine?
- Beta alanine thiab L alanine yog ob qho sib txawv ntawm cov amino acids.
- Lawv yog ib txwm tshwm sim amino acids.
- Ob lub amino acids muaj tib lub mis molecular: C3H7NO2.
- Cov amino acids no muaj kev siv sib txawv.
Qhov txawv ntawm Beta Alanine thiab L Alanine yog dab tsi?
Beta-alanine yog cov amino acid uas tsis yog-proteinogenic, thaum L alanine yog proteinogenic amino acid. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm beta alanine thiab L alanine. Tsis tas li ntawd, nyob rau hauv beta-alanine, cov amino pawg ntawm cov amino acid txuas nrog β carbon, tab sis nyob rau hauv L alanine, cov amino pawg ntawm cov amino acid txuas nrog α carbon.
Cov ntawv qhia hauv qab no nthuav tawm qhov sib txawv ntawm beta alanine thiab L alanine hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Beta Alanine vs L Alanine
Amino acids yog cov organic molecules uas sib xyaw ua cov proteins. Beta alanine thiab L alanine yog ob hom amino acids. Beta alanine yog ib qho uas tsis yog-proteinogenic amino acid, thaum L alanine yog proteinogenic amino acid. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm beta alanine thiab L alanine.
