Kev poob ntawm kev sib haum xeeb entropy yog ib qho kev koom tes loj hauv cov thermodynamics ntawm cov protein folding Txawm li cas los xij, kev txiav txim siab tseeb ntawm qhov ntau tau ua pov thawj nyuaj. Peb xam qhov kev poob no siv cov kev sim molecular dynamic simulations ntawm ob qho tib si cov protein thiab ib lub xeev muaj tseeb denatured ensemble.
Dab tsi yog conformational entropy protein?
Conformational entropy is the entropy txuam nrog tus naj npawb ntawm conformations ntawm ib molecule. … Nyob rau hauv cov proteins, qaum dihedral ces kaum thiab sab saw rotamers feem ntau yog siv raws li tsis, thiab nyob rau hauv RNA lub hauv paus khub qauv yuav siv tau.
Qhov twg muaj ntau dua conformational entropy ib folded protein los yog unfolded ib?
Qhov kev sib koom ua ke ntawm cov saw hlau polypeptide yog qhov loj dua rau unfolded xeev piv rau lub xeev ntau dua qub uas muaj ntau qhov chaw txwv tsis pub muaj. Yog li ntawd, qhov kev pab cuam no ruaj khov rau lub xeev unfolded (ΔSconf > 0).
Yuav ua li cas txiav txim siab cov protein sib haum thiab qhov teeb meem cuam tshuam nrog cov protein folding yog dab tsi?
Cov qauv tseem ceeb ntawm cov protein, nws cov kab sib txuas amino-acid, txiav txim siab nws qhov kev sib haum xeeb. Cov amino acid residues tshwj xeeb thiab lawv txoj hauj lwm hauv cov saw hlau polypeptide yog qhov kev txiav txim siab rau qhov twg ntawm cov protein folds ze ua ke thiab tsim nws cov qauv peb sab.
Yam dab tsi cuam tshuam rau qhov folding ntawm cov protein?
Protein folding yog txheej txheem rhiab heev uas cuam tshuam los ntawm ntau yam sab nraud suav nrog hluav taws xob thiab hlau nplaum, qhov kub thiab txias, pH, tshuaj, qhov chaw txwv thiab molecular crowdingCov xwm txheej no cuam tshuam rau lub peev xwm ntawm Proteins txhawm rau txhawm rau hauv lawv cov ntawv ua haujlwm raug.

Cuam tshuam lossis cuam tshuam li cas cuam tshuam kev sib txuas lus?
Txhua zaus peb tham lossis mloog, muaj tej yam uas nkag mus rau hauv txoj kev sib txuas lus meej-yam uas cuam tshuam rau tus neeg txais tau cov lus los ntawm tus xa. Qhov kev cuam tshuam no yog hu ua " noise," thiab muaj ntau hom suab nrov uas tuaj yeem ua rau cov lus raug txhais tsis raug .
Puas yog qhov cuam tshuam nrog tus neeg siv cuam tshuam?
Cov neeg siv cuam tshuam yog nkag mus rau cov ntsiab lus uas cov neeg siv cuam tshuam nrog cov qauv tsim… Graphical user interfaces (GUIs)-Cov neeg siv cuam tshuam nrog cov duab sawv cev ntawm cov tswj digital. Lub computer lub desktop yog GUI.
Puas yog cov tog cuam tshuam lossis cov tog neeg cuam tshuam?
" Affected" txhais tau tias " cuam tshuam, tsim kev cuam tshuam rau, hloov pauv hauv ib txoj kev." "Effected" txhais tau tias "tua, coj los, tsim ib yam dab tsi." Koj puas tau cuam tshuam lossis cuam tshuam los ntawm qee yam?
Puas yog Excel muaj qhov cuam tshuam cuam tshuam?
Ntau tus neeg xav cuam tshuam cov ntaub ntawv lawv tau digitized nrog Dagra hauv Microsoft Excel. Hmoov tsis zoo Excel tsis muaj kev cuam tshuam kev ua haujlwm tab sis muaj txoj hauv kev yooj yim . Koj ua kev cuam tshuam hauv Excel li cas?
Puas yog qhov kev thov tsis raug cuam tshuam cuam tshuam rau tus nqi pov hwm?
Feem ntau, tsis muaj qhov yuam kev yuav tsis ua rau koj cov nqi fajseeb khomob nceQhov no yog vim tus neeg ua txhaum cai tus kws kho mob yuav lav koj cov nqi kho mob thiab kho tsheb. Yog tias koj tus neeg tuav pov hwm tsis tas yuav rho nyiaj tawm, koj cov nqi them yuav tsis nce .
