Qhov sib txawv tseem ceeb ntawm alanine thiab beta alanine yog tias alanine ib txwm muaj tsawg dua li beta-alanine.
Alanine yog alpha amino acid pab tau rau hauv biosynthesis ntawm cov protein. Beta-alanine yog ib qho tsis tseem ceeb amino acid uas tsim ib txwm nyob hauv lub cev thiab pab tsim cov carnosine.
Alanine yog dab tsi?
Alanine yog alpha amino acid pab tau rau hauv biosynthesis ntawm cov protein. Nws lub cim yog Ala lossis A. Cov protein no muaj pawg amine thiab pawg carboxylic acid txuas nrog lub hauv paus carbon atom uas tuaj yeem nqa cov methyl pawg sab saw. Lub npe IUPAC ntawm cov khoom no yog 2-aminopropanoic acid. Peb tuaj yeem faib nws ua ib qho nonpolar, aliphatic alpha amino acid. Raws li qee qhov kev mob lom neeg, alanine nyiam nyob ua ib qho zwitterion. Hauv qhov zwitterion no, pawg amino yog protonated thaum pawg carboxylic acid yog deprotonated.
Daim duab 01: Cov Qauv Tshuaj ntawm Alanine Molecule
Alanine yog ib qho tsis tseem ceeb amino acid vim tias peb tuaj yeem ua ke nws metabolically hauv lub cev. Yog li ntawd, nws tsis tas yuav tsum tau suav nrog hauv kev noj haus. Ntxiv mus, alanine yog encoded los ntawm tag nrho cov codons, uas pib nrog GC.
Muaj ob isomers ntawm alanine hu ua L-alanine thiab D-alanine. L isomer yog daim ntawv sab laug, thaum D isomer yog daim ntawv sab xis. Peb tuaj yeem pom txoj cai D-alanine hauv cov polypeptides hauv qee cov kab mob ntawm cov phab ntsa ntawm tes, qee cov tshuaj tua kab mob, thiab hauv cov ntaub so ntswg ntawm ntau cov crustaceans thiab molluscs xws li osmolytes.
Beta Alanine yog dab tsi?
Beta alanine yog ib qho tsis tseem ceeb amino acid uas tsim ib txwm nyob hauv lub cev thiab pab tsim cov carnosine. Carnosine yog ib qho tseem ceeb sib xyaw uas tuaj yeem ua lub luag haujlwm tseem ceeb hauv cov leeg mob thaum ua kev tawm dag zog siab.
Daim duab 02: Cov Qauv Tshuaj ntawm L Alpha Alanine thiab Beta Alanine
Beta alanine tuaj yeem pib khaus ib ntus thiab tingling ntawm daim tawv nqaij, xws li ntawm caj dab, xub pwg, thiab caj npab yog tias peb noj ntau ntau. Qhov kev xav no yog hu ua paresthesia. Nws tuaj yeem tsis xis nyob me ntsis, tab sis tsis tas yuav tsum ntshai txog qhov no.
Thaum noj qhov ncauj, beta-alanine tuaj yeem ua rau qee qhov kev mob tshwm sim xws li dej ntws tawm thiab tingling. Txawm li cas los xij, yog tias peb noj cov ntsiav tshuaj uas muaj beta-alanine ntau dua li haus cov tshuaj ua los ntawm cov tshuaj no (cov tshuaj ua los ntawm beta-alanine hmoov), cov kev mob tshwm sim tuaj yeem txo.
Qhov txawv ntawm Alanine thiab Beta Alanine yog dab tsi?
Alanine yog alpha amino acid pab tau rau hauv biosynthesis ntawm cov protein. Beta alanine yog ib qho tsis tseem ceeb amino acid uas tsim ib txwm nyob hauv lub cev thiab pab tsim cov carnosine. Qhov sib txawv tseem ceeb ntawm alanine thiab beta alanine yog tias alanine ib txwm muaj tsawg dua li beta-alanine. Ntxiv mus, alanine muaj txiaj ntsig zoo hauv kev tsim cov protein ntau sib txawv. Lub caij no, beta alanine tshwj xeeb yog qhov tseem ceeb hauv kev tsim cov carnosine, uas yog lub luag haujlwm tseem ceeb hauv kev ua kom cov leeg mob siab thaum peb ua ntau qhov kev tawm dag zog.
Cov duab hauv qab no nthuav tawm qhov sib txawv ntawm alanine thiab beta alanine hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Alanine vs Beta Alanine
Alanine yog ib qho amino acid, thaum beta alanine yog ib qho derivative ntawm alanine. Qhov sib txawv tseem ceeb ntawm alanine thiab beta alanine yog tias alanine ib txwm muaj tsawg dua li beta-alanine. Alanine yog qhov tseem ceeb hauv kev tsim cov protein sib txawv. Beta alanine, ntawm qhov tod tes, tuaj yeem pab tsim cov carnosine, qhov sib xyaw tseem ceeb hauv cov leeg mob siab rau kev ua haujlwm siab.
