Ntsev hydrolysis yog txhais raws li tus txheej txheem uas a ntsev reacts nrog dej kom rov qab cov kua qaub thiab lub hauv paus. Qhov no hu ua acidic hydrolysis . Ntsev hydrolysis tej zaum yuav raug txhais raws li cov tshuaj tiv thaiv ntawm cation lossis anion ntawm cov ntsev nrog dej los tsim acidic los yog yooj yim daws.
Ua kom pom qhov no, cov ntsev twg yuav tsis raug hydrolysis?
Cov ntsev ntawm cov kua qaub thiab cov hauv paus muaj zog zoo li N A C, K C l NaCl , KCl NaCl, KCl tsis dhau hydrolysis. Hauv qhov no, tsis yog cov cations lossis anion dhau los hydrolysis.
Tsis tas li ntawd, hom ntsev twg tau txais hydrolysis? Ammonium ion tsim undergoes hydrolysis los ua ammonium hydroxide thiab H^+ ions. Raws li peb paub ammonium hydroxide yog lub hauv paus tsis muaj zog, nws tseem nyob hauv kev daws teeb meem.
Raws li hydrolysis, ntsev tau muab faib ua peb pawg:
- Acidic ntsev.
- Ntsev ntsev
- Ntsev nruab nrab.
Xav txog qhov no, yuav ua li cas tshwm sim thaum ntsev dhau hydrolysis?
Piav qhia: Hydrolysis yog thim rov qab ntawm neutralization. Thaum twg ntsev yog ntxiv rau hauv dej, tom qab ntawd cation, anion lossis ob qho tib si ions ntawm ntsev hnov mob nrog dej thiab yog tias cov tshuaj ua kua qaub lossis yooj yim ces nws yog hydrolysis txheej txheem. Thaum lub sij hawm cation ntsev reacts nrog dej, lub hauv paus tsis muaj zog thiab kua qaub yog tsim.
Puas yog NaCl raug hydrolysis?
NaCl yog ntsev ntawm ib tug muaj zog acid - muaj zog puag ua ke (HCl thiab NaOH). Rau ntsev rau undergo hydrolysis , tsawg kawg yog ib qho ntawm cov niam txiv sib txuas (xws li cov kua qaub lossis lub hauv paus los yog ob qho tib si) yuav tsum tsis muaj zog. Cov ntsev tau los ntawm cov kua qaub -muaj zog hauv paus ua ke yuav tsis yuav tsum tau hydrolysis.

Lub hom phiaj ntawm cov xauv ntsev yog dab tsi?
Lub ntsuas phoo ntsev yog ib qho khoom siv sib xyaw ua ke tsis tu ncua uas tswj hwm txoj hlab ntshav ntawm ib leeg ib leeg tso cai rau ob qho kev tswj hwm cov tshuaj IV ib ntus yam tsis tas siv cov kua dej txuas ntxiv thiab rau lub sijhawm xav tau ntawm cov qauv ntshav. Qhov no tiv thaiv venipuncture rov ua rau tus neeg mob xis nyob
Bile ntsev raws plab yog dab tsi?
Cov kua qaub kua qaub (BAD) yog ib yam mob uas cov kua tsib kua qaub tsis tau ua tiav hauv cov txheej txheem zom zaub mov, ua rau muaj cov tsos mob ntawm raws plab raws plab. Qhov mob no tseem tuaj yeem raug hu ua bile acid malabsorption (BAM). Txawm li cas los xij, kev tshawb fawb xyoo 2009 qhia tias qhov xwm txheej yuav tsis tas li vim yog malabsorption
Puas yog ntsev ntsev ntawm tes nyab xeeb rau menyuam yaus?
Cov ntaub so ntswg ntsev, tseem hu ua ntsev ntawm tes lossis ntsev ntsev biochemic, tau pom ib txwm nyob hauv cov pob zeb thiab av, nroj tsuag thiab tsiaj txhu (suav nrog tib neeg). Cov ntaub so ntswg ntsev yog pheej yig, thiab muaj kev nyab xeeb rau siv rau txhua tus, los ntawm menyuam yaus mus rau cov neeg mob ntshav qab zib thiab txawm tias tsiaj. Lawv feem ntau tuaj hauv cov ntsiav tshuaj
Lub hom phiaj ntawm txhua feem hauv mannitol ntsev agar phaj yog dab tsi?
Mannitol ntsev Agar muaj peptones thiab nqaij nyug extract, uas muab nitrogen, vitamins, minerals thiab amino acids tseem ceeb rau kev loj hlob. Qhov 7.5% cov ntsiab lus ntawm sodium chloride ua rau ib nrab lossis ua tiav kev tiv thaiv kab mob ntawm cov kab mob uas tsis yog staphylococci
Dab tsi yog qhov ua haujlwm ntawm cov ntsev ntsev hauv kev zom zaub mov?
Cov kua ntsev tso tawm cov rog thiab zom lawv mus rau hauv me me uas muab cov enzyme lipase thaj chaw ntau dua los ua thaum lub sijhawm zom cov rog. Kev zom zaub mov carbohydrate pib hauv lub qhov ncauj nrog salivary amylase
