Tetracyclins yog ib hom tshuaj tshuaj tua kab mob uas suav nrog tus thawj tetracycline nrog rau doxycycline thiab minocycline. Cov no tshuaj tua kab mob khi rau A qhov chaw ntawm 30s ribosome, tiv thaiv tRNA los ntawm kev nqa cov amino acids tshiab. Yog tias tRNA tsis tuaj yeem txuas rau ribosome, ces tsis muaj qhov tshiab cov proteins tuaj yeem ua tau.
Yog li ntawd, cov tshuaj tua kab mob twg inhibit protein synthesis?
Cov tshuaj tua kab mob tuaj yeem tiv thaiv kev sib txuas ntawm cov protein los ntawm kev tsom mus rau 30S subunit, piv txwv xws li spectinomycin, tetracycline, thiab aminoglycosides kanamycin thiab streptomycin, lossis rau 50S subunit, piv txwv xws li clindamycin, chloramphenicol linezolid, thiab macrolides erythromycin, Tsis tas li ntawd, cov tshuaj tua kab mob twg tsis cuam tshuam kev txhais cov kab mob? Lincomycin thiab clindamycin yog cov inhibitors tshwj xeeb ntawm peptidyl transferase, thaum macrolides tsis ncaj qha inhibit enzyme.
Ntawm no, cov tshuaj tua kab mob uas inhibit protein synthesis ua haujlwm li cas?
Tag nrho cov tshuaj tua kab mob lub hom phiaj kab mob protein synthesis ua yog li los ntawm kev cuam tshuam nrog cov kab mob ribosome thiab inhibiting nws txoj haujlwm. Lub ribosome yuav tsis zoo li lub hom phiaj zoo rau kev xaiv toxicity, vim hais tias txhua lub hlwb, nrog rau peb tus kheej, siv ribosomes rau protein synthesis.
Cov tshuaj tua kab mob twg tuaj yeem tiv thaiv kev tsim cov protein los ntawm kev tiv thaiv kab mob ribosomes los ntawm kev ua haujlwm?
Tetracyclines thiab Tigecycline (ib qho glycylcycline ntsig txog rau tetracyclines) thaiv lub site A ntawm lub ribosome , tiv thaiv Kev sib txuas ntawm aminoacyl tRNAs.

Qhov twg ntawm cov tshuaj tiv thaiv kab mob ua rau cov ntawv cog lus tawg?
Lub zog ua kom muaj zog yog lub zog uas yuav tsum tau nqus kom muaj tshuaj lom neeg pib. Thaum lub zog ua kom txaus ntxiv rau cov reactants, cov ntawv cog lus hauv cov reactants tawg thiab cov tshuaj tiv thaiv pib
Vim li cas thiaj siv cov tshuaj tua kab mob hauv cov tshuaj distillation?
Lub hom phiaj ntawm kev sib tsoo granules Saib Lawv nres, uas qhov tshwm sim tam sim ntawd ntawm vapor npuas nyob rau hauv cov kua kub ua rau upwards splashing. Theanti-bumping granules ua raws li lub hom phiaj rau theformation ntawm vapor cia du boiling
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
Cov tshuaj tua kab mob dab tsi inhibits protein synthesis?
Cov tshuaj tua kab mob tuaj yeem tiv thaiv kev sib txuas ntawm cov protein los ntawm kev tsom mus rau 30S subunit, piv txwv xws li spectinomycin, tetracycline, thiab aminoglycosides kanamycin thiab streptomycin, lossis rau 50S subunit, piv txwv xws li clindamycin, chloramphenicol, linezolid, thiab thromycrolid
Dab tsi yog cov tshuaj tua kab mob cuam tshuam nrog cov protein synthesis?
Erythromycin, macrolide, khi rau 23S rRNA tivthaiv ntawm 50S ribosome thiab cuam tshuam nrog kev sib dhos ntawm 50S subunits. Erythromycin, roxithromycin, thiab clarithromycin tag nrho tiv thaiv elongation ntawm cov kauj ruam transpeptidation ntawm synthesis los ntawm thaiv cov 50S polypeptide export qhov
