Acetylsalicylic acid yog a tsis muaj zog acid, thiab tsawg heev ntawm nws yog ionized hauv plab tom qab noj qhov ncauj. Acetylsalicylic acid yog sai absorbed los ntawm lub cell membrane nyob rau hauv acidic mob ntawm lub plab.
Yuav ua li cas cov kua qaub yog acetylsalicylic?
Cov tshuaj Aspirin (acetylsalicylic acid) Aspirin yog npaj los ntawm cov tshuaj synthesis los ntawm salicylic acid, los ntawm acetylation nrog acetic anhydride. Qhov hnyav molecular ntawm aspirin yog 180.16g / mol. Nws tsis muaj ntxhiab tsw, tsis muaj xim rau dawb crystals lossis crystalline hmoov.
Acetylsalicylic chav kawm twg yog nyob rau?
Aspirin yog cais raws li tsis xaiv cyclooxygenase (COX) inhibitorthiab muaj nyob rau hauv ntau cov koob tshuaj thiab cov ntawv, suav nrog cov ntsiav tshuaj chewable, suppositories, ncua kev tso tawm formulations, thiab lwm yam. Acetylsalicylic acid yog ib qho ua rau muaj kev phom sij heev rau cov menyuam yaus.
Vim li cas Aspirin thiaj li muaj kua qaub?
Science Concepts: Aspirin yog a tsis muaj zog acid thiab nws nyiam ionize (muab H atom) hauv nruab nrab aqueous ntawm pH siab. Cov tshuaj tsis hla cov kab mob lom thaum lawv ionized. Nyob rau hauv ib puag ncig pH qis zoo li lub plab (pH=2), cov tshuaj aspirin feem ntau sib koom ua ke thiab hla daim nyias nyias mus rau hauv cov hlab ntsha yooj yim.
Puas yog aspirin yog lub hauv paus lossis acid?
Aspirin nws tus kheej yog ib qho tshuaj acidic thiab ua rau plab hnyuv thiab regurgitation uas tuaj yeem ua rau qispH ntawm qhov ncauj [7].
