Sucrose khi mus rau qhov chaw nquag ntawm sucrase, thiab qhov no ua rau muaj kev ntxhov siab ntawm kev sib raug zoo ntawm 2 suab thaj uas ua rau qab zib . Cov nyiaj ua haujlwm tawg, tso cov piam thaj thiab fructose.
Yog li ntawd, dab tsi tshwm sim thaum lub sij hawm hydrolysis ntawm sucrose?
Thaum twg qab zib yog hydrolyzed nws tsim ua 1: 1 sib xyaw ntawm cov piam thaj thiab fructose. Nws yog hu ua invert qab zib vim hais tias lub kaum sab xis ntawm qhov tshwj xeeb kev sib hloov ntawm lub tiaj polarized lub teeb hloov los ntawm qhov zoo mus rau qhov tsis zoo vim muaj qhov pom ntawm cov isomers ntawm qhov sib xyaw ntawm cov piam thaj thiab fructose qab zib.
Ib yam li ntawd, cov molecule twg yog cov khoom lag luam ntawm cov tshuaj tiv thaiv ntawm sucrose thiab Sucrase? Ib qho piv txwv: Sucrase, 400 npaug ntawm qhov loj ntawm nws cov substrate sucrose, faib cov sucrose rau hauv nws cov khoom. suab thaj , yog qabzib thiab fructose qab zib . Lub sucrose khoov cov sucrose, thiab ua kom muaj kev sib raug zoo ntawm cov qabzib thiab fructose qab zib . Cov dej molecules koom rau hauv thiab ua kom cov cleavage nyob rau hauv ib feem ntawm ib tug thib ob.
Raws li, lactase puas tuaj yeem zom sucrose?
Lwm yam disaccharides, xws li qab zib thiab lactose tawg lawm los ntawm sucrase thiab lactase , raws. Sucrase rhuav tshem sucrose (los yog "cov suab thaj") rau hauv qabzib thiab fructose, thiab lactase tawg lactose (los yog "mis qab zib") rau hauv qabzib thiab galactose.
Dab tsi tshwm sim thaum koj ua kom sov sucrose?
Dab tsi koj ua thaum twg koj sov zoo li qab zib qab zib yog koj yog lub cev qhuav dej nws . Lub crystalline qauv ntawm qab zib tawg thiab cov lwg me me ua rau piam thaj thiab fructose thiab tom qab ntawd poob dej thiab tom qab ntawd dhau los ua isomers thiab polymerize los ua caramel, xim liab-txiv kab ntxwv xim khov ntawm chav sov.

Dab tsi yuav tsum tsis txhob muab txoj cai thaum nws tau txiav txim siab tias nws ib txwm cuam tshuam nrog cov txheej txheem kab mob?
Tus lej cim cov tsos mob yuav tsum tsis txhob raug xaiv thaum nws tau txiav txim siab tias nws ib txwm cuam tshuam nrog cov txheej txheem kab mob. Nrog rau kev kis tus kab mob (Cov M02) ntawm cov pob qij txha vim yog kis kab mob los yog kab mob sib kis nyob rau lwm qhov, tus coder tau hais qhia rau 'tus lej ua ntej' tus kab mob hauv qab
Nws txhais li cas thaum koj nias ntawm koj cov tawv nqaij thiab nws nyob qis qis?
Edema yog tshwm sim los ntawm cov kua dej ntau dhau hauv cov ntaub so ntswg. Lwm cov tsos mob edema yuav muaj xws li daim tawv nqaij uas ncab los yog ci iab; daim tawv nqaij uas nyob twj ywm tom qab raug nias tsawg kawg tsib vib nas this; thiab nce hauv plab me me. Edema tuaj yeem cuam tshuam rau lub ntsws thiab ua rau ua pa luv uas xav tau kev kho mob tam sim
Vim li cas kuv tus miv zom nws cov hniav thaum kuv muab nws?
Nyob zoo Isabel, cov hniav sib tsoo hauv miv tsis ntau thiab feem ntau qhia tias mob. Yuav muaj ntau qhov laj thawj nws tau ua qhov no, suav nrog kab mob hniav, lossis lwm qhov mob
Yuav ua li cas rau cov nqaij du thaum nws cog lus?
Smooth nqaij contraction yog tshwm sim los ntawm zawv zawg ntawm myosin thiab actin filaments (ib tug zawv zawg filament mechanism) ntawm ib leeg. Lub zog rau qhov no tshwm sim yog muab los ntawm hydrolysis ntawm ATP. Tsis zoo li cov hlab plawv thiab pob txha pob txha, cov leeg du tsis muaj calcium-binding protein troponin
Nws hu li cas thaum nws tsis mob qog noj ntshav?
Zoo heev. Hais txog cov qog uas tsis yog mob qog noj ntshav. Cov qog nqaij hlav feem ntau tsis ua rau cov nqaij nyob ze lossis kis mus rau lwm qhov hauv lub cev. Biopsy. Kev tshem tawm cov nqaij me me rau kev kuaj mob hauv lub tshuab tsom iav
