Qhov sib txawv tseem ceeb ntawm sab laug thiab sab tes xis amino acids yog tias pawg amine ntawm sab laug-tes amino acid tshwm sim nyob rau sab laug ntawm cov molecule whereas pawg amine ntawm txoj cai amino acids nyob rau hauv txoj cai- sab tes.
Chirality yog qhov tshwm sim tseem ceeb hauv cov tshuaj lom neeg. Nws piav txog qhov muaj cov pa roj carbon atom, uas muaj plaub pawg sib txawv txuas rau nws. Qhov ntawd txhais tau tias; chiral compound muaj asymmetric carbon centre. Sab laug thiab sab tes xis amino acids yog ob hom organic compounds uas muaj chiral centres.
Left Handed Amino Acids yog dab tsi?
Sab laug tes amino acids yog cov stereoisomers uas cov amine pawg ntawm cov molecule muaj nyob rau sab laug. Peb kuj hu lawv ua L-amino acids thiab. Thaum xav txog cov qauv dav dav, hom amino acid molecules no muaj lub hauv paus chiral carbon, hydrogen atom txuas rau cov pa roj carbon monoxide rau saum toj, pawg alkyl txuas rau hauv qab, pawg amine ntawm sab laug thiab pawg carboxylic ntawm sab xis.

Cov tebchaw no tshwm sim nyob rau hauv tag nrho cov proteins ntawm cov tsiaj, nroj tsuag, fungi, thiab lwm yam. Tsis tas li ntawd, cov hlwb siv lawv los tsim cov proteins. Thaum xav txog lawv lub luag haujlwm hauv cov kab mob lom, lawv tuaj yeem ua raws li cov enzymes, xws li cov tshuaj hormones, thiab lwm yam.
Dab tsi yog Txoj Cai Amino Acids?
Txoj cai amino acids yog cov stereoisomers uas cov amine pawg ntawm cov molecule muaj nyob rau sab xis. Ntxiv mus, peb tuaj yeem hu lawv D-amino acids. Thaum xav txog cov qauv dav dav ntawm cov molecules, muaj lub hauv paus chiral carbon atom txuas nrog hydrogen atom nyob rau sab saum toj, ib pawg alkyl nyob hauv qab, pawg amine ntawm sab xis thiab pawg carboxylic acid ntawm sab laug-tes. sab.

Feem ntau, tsis muaj txoj cai amino acid molecules koom ua ke rau hauv cov protein los ntawm cov hlwb. Txawm li cas los xij, qee qhov ntawm lawv tshwm sim hauv peptidoglycan cell phab ntsa ntawm cov kab mob. Ntxiv rau qhov ntawd, qee qhov ntawm cov tshuaj no (piv txwv li D-serine) ua cov tshuaj neurotransmitter hauv peb lub hlwb.
Dab tsi yog qhov txawv ntawm Sab laug thiab Txoj Cai Amino Acids?
Left-handed amino acids yog cov stereoisomers uas cov amine pawg ntawm cov molecule muaj nyob rau sab laug-tes thaum sab tes xis amino acids yog cov stereoisomers uas pawg amine ntawm cov molecule muaj nyob rau sab xis. sab. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm sab laug thiab sab tes xis amino acids, Ntxiv mus, lwm qhov sib txawv tseem ceeb ntawm sab laug thiab sab tes xis amino acids yog tias sab laug tes amino acid muaj lub hauv paus chiral carbon, hydrogen atom nyob rau sab saum toj, ib pawg alkyl hauv qab, amine pawg ntawm sab laug tes. sab thiab pawg carboxylic ntawm sab tes xis. Tab sis txoj cai amino acid muaj lub hauv paus chiral carbon, hydrogen atom nyob rau sab saum toj, ib pawg alkyl nyob hauv qab, pawg amine ntawm sab xis thiab pawg carboxylic ntawm sab laug.
Cov hauv qab no infographic ntawm qhov sib txawv ntawm sab laug thiab sab tes xis cov amino acids nthuav tawm cov kev sib txawv no hauv daim ntawv teev npe.
Summary – Sab laug vs Txoj Cai Tes Amino Acids
Ob leeg sab laug thiab sab tes xis amino acids muaj txiaj ntsig zoo rau cov hlwb hauv cov haujlwm sib txawv. Hauv cov ntsiab lus, qhov sib txawv tseem ceeb ntawm sab laug thiab sab tes xis amino acids yog tias pawg amine ntawm sab laug tes amino acid tshwm sim nyob rau sab laug ntawm cov molecule whereas pawg amine ntawm txoj cai amino acids nyob rau sab xis.
