Arginine vs L-Arginine
Arginine yog ib qho α- amino acid feem ntau abbreviated li ' Arg' uas yog thawj zaug cais los ntawm Swiss chemist npe hu ua Ernst Schultze hauv 1886 los ntawm lupine seedling extract. Qhov tseem ceeb ntawm lub caij 'N' yog qhov tshwj xeeb hauv cov qauv tshuaj ntawm Arginine thiab yog li no, muaj txiaj ntsig zoo hauv kev sib txuas ntawm cov protein. Nyob ntawm seb qhov stereochemistry, cov qauv tshuaj ntawm Arginine ib yam li lwm cov qauv tshuaj lom neeg tuaj yeem taw qhia ntau txoj hauv kev. Yog li ntawd, muaj ob hom kev paub ntawm cov qauv no xws li D-Arginine thiab L-Arginine. Feem ntau D-Arginine raug xa mus rau hauv daim ntawv tsis muaj zog ntawm L-Arginine.
Arginine yog dab tsi?
Zoo li lwm yam amino acid, Arginine ib yam nkaus muaj plaub qhov tseem ceeb hauv nws cov qauv tshuaj. Pawg COO, pawg H atom, NH2 thiab pawg R uas yog cov saw hlau sab. R pab pawg yog tsim los ntawm 3 Carbon aliphatic ncaj saw, thiab qhov kawg ntawm cov saw yog capped nrog ib pab pawg neeg guanidinium uas yog centralized nyob ib ncig ntawm lub 'N' keeb. Cov pab pawg neeg guanidinium tseem muaj txiaj ntsig zoo hauv cov kua qaub, nruab nrab thiab cov pH yooj yim tshaj tawm thiab yog li qhia cov khoom siv yooj yim. Lub conjugation tam sim no nyob rau hauv pawg guanidinium thiab COO- pab pawg muaj ntau lub peev xwm rau chemistry.
D thiab L daim ntawv lo hauv lub tso suab-tshuaj lom neeg tsis cuam tshuam rau kev ua haujlwm optically nrog d / l (dextrorotatory / levorotatory) labelling. Nws muab koj cov ntaub ntawv hais txog kev teeb tsa ntawm cov ntsiab lus hauv ib qho qauv thiab muaj txiaj ntsig hauv kev txheeb xyuas daim ntawv nquag ntawm cov khoom sib xyaw. Los ntawm kev ua raws li txoj cai yooj yim hu ua 'CORN' txoj cai, nws muaj peev xwm txheeb xyuas qhov twg isomeric tsim ib qho amino acid belongs rau, los ntawm D thiab L. Thaum cov pab pawg, CO OH, R, NH2 thiab H yog teem ib ncig ntawm lub chiral center thiab thaum saib lub molecule los ntawm lub opposite sab ntawm lub H atom (ntsig rau H atom, uas tam sim no yuav tom qab), yog hais tias tus txheej txheem ntawm lub Cov pab pawg CO-R-N yog counter-clockwise, ces nws yog hais tias nyob rau hauv daim ntawv L thiab, yog hais tias cov pab pawg neeg teem clockwise, nws yuav nyob rau hauv daim ntawv D. Ntawm no, L-Arginine yog daim ntawv nquag ntawm ob thiab feem ntau pom muaj nyob hauv cov proteins ntuj.
L-Arginine yog dab tsi?
L-Arginine yog ib qho tsis tseem ceeb amino acid suav nrog hauv 20 cov amino acids ntau tshaj plaws, txhais tau tias nws tsis tas yuav nyob ntawm kev noj zaub mov kom tau txais nws. Txawm li cas los xij, feem ntau, txoj hauv kev biosynthetic tsis tsim qhov xav tau ntawm L-Arginine li no yuav tsum tau txais los ntawm kev noj zaub mov kom tsawg. Arginine muaj nyob rau hauv ntau yam khoom noj; cov khoom noj siv mis (cheese, mis nyuj thiab lwm yam), nqaij nyuj, nqaij npuas, nqaij nruab deg, nqaij qaib, hmoov nplej, chickpeas, txiv ntseej, thiab lwm yam. L-Arginine kuj tau muag hauv khw muag tshuaj ntxiv thaum noj ntxiv rau kev kho mob. Ib yam li nws pab tsim cov protein, L-Arginine kuj tseem pab tshem tawm cov ammonia hauv lub cev, uas yog cov khoom pov tseg thiab ua rau kom tso tawm cov tshuaj insulin. Nws kuj ua raws li cov neeg ua ntej rau nitric oxide uas pab kom nws so ntawm cov hlab ntsha, ua rau Arginine ua lub neej cawm siav rau cov neeg mob plawv.
Yog li, feem ntau, L-Arginine muab kev txhawb nqa rau lub cev hauv kev kho qhov txhab, ua kom lub cev tsis muaj zog thiab cov tshuaj hormones thiab pab lub raum tshem tawm cov khoom pov tseg. Txawm li cas los xij, kev noj tshuaj ntxiv ntawm Arginine yuav tsum tau ua raws li kev tshuaj xyuas kev kho mob vim tias kev noj tshuaj ntau dhau tuaj yeem ua rau muaj kev phiv ntau yam thiab tuaj yeem ua rau muaj kev phom sij heev.
Qhov txawv ntawm Arginine thiab L-Arginine yog dab tsi?
• Arginine yog lub npe uas tau muab rau cov qauv tshuaj ntawm cov khoom sib txuas whereas, L-Arginine tau sau npe rau kev txheeb xyuas qhov tseeb stereochemistry ntawm cov tshuaj nquag.
• Arginine yog ib qho α-amino acid, thiab nws L daim ntawv poob ntawm 20 feem ntau cov amino acids xav tau rau kev tsim cov proteins.
• Thaum D-Arginine ua haujlwm tsis ua haujlwm ntawm L-Arginine thiab tsuas yog pab txhawm rau kuaj lub hom phiaj los hloov tshuaj L-Arginine, tom kawg tau nthuav tawm ntau yam txiaj ntsig zoo rau lub cev thiab tshwj xeeb tshaj yog ua raws li qhov ua ntej rau ib qho muaj zog neurotransmitter, uas pab nyob rau hauv so ntawm cov hlab ntsha uas nyob rau hauv lem yuav pab tua kab mob plawv
