DEFINITION: Lub peev xwm ntawm cov tshuaj sib xyaw kom tshem tawm cov tshuaj pharmacological / kev kho mob muaj feem cuam tshuam nrog kev cuam tshuam ntawm ntau yam lub cev thiab tshuaj (physicochemical) cov khoom ntawm cov tshuaj lom neeg ntawm bio molecule uas nws cuam tshuam nrog.
Vim li cas thiaj tseem ceeb kom paub txog lub cev muaj zog ntawm cov tshuaj?
Nws yog thaj chaw tseem ceeb txij li nqus tshuaj nyob ntawm kev xav txog lub cev. … qhov no yog qhov tseem ceeb tshaj plaws kom paub txog cov khoom siv physicochemical, qhov kev kwv yees thiab cuam tshuam cov flux, bioavailability, ntawm cov tshuaj hauv TDDS, lossis TDDS microemulsion.
Yuav ua li cas yog lub zog ntawm lub cev?
Physico-chemical zog yog tus yam ntxwv ntawm lub cev thiab tshuaj lom neeg ntawm ib yam khoom. Cov no suav nrog cov tsos, qhov kub thiab txias, qhov ntom ntom, volatility, dej solubility thiab flammability thiab lwm yam.
Puas tshuaj stability yog physicochemical khoom?
Zaj. Yuav tsum muaj kev paub txog kev kho mob thiab physicochemical ntawm cov tshuaj uas tsim nyog los txiav txim qhov tsim nyog thiab kev xa khoom ntawm cov tshuaj. … Nyob rau hauv seem physicochemical, ob qho tseem ceeb tshaj plaws physicochemical zog rau kev xa tshuaj, solubility thiab stability, tau tham.
Vim li cas physicochemical khoom tseem ceeb?
Lub cev muaj zog ntawm cov neeg sib tw sib tw ua si lub luag haujlwm tseem ceeb hauv kev tsim cov tshuaj tua kab tshiab. Cov tshuaj tua kab yuav tsum tau nqus los ntawm cov kab tsuag, thauj mus rau qhov chaw lub hom phiaj, thiab tom qab ntawd cuam tshuam nrog cov protein. Hydrophobicity tseem ceeb heev rau cov txheej txheem no.

Lub ntsiab lus ntawm physicochemical zog yog dab tsi?
Physico-chemical zog yog cov yam ntxwv ntawm lub cev thiab tshuaj lom neeg ntawm ib yam khoom. Cov no suav nrog cov tsos, qhov kub thiab txias, qhov ntom ntom, volatility, dej solubility thiab flammability thiab lwm yam . Yuav ua li cas piv txwv ntawm physicochemical zog?
Thaum cov kuab tshuaj evaporates dab tsi tshwm sim rau qhov concentration ntawm cov tshuaj?
Qhov no txhais tau hais tias yog tias koj cov kuab tshuaj evaporating thiab qhov kub thiab txias tsis tu ncua, ces solute yuav precipitate tawm ntawm cov tshuaj. Qhov concentration ntawm cov tshuaj yuav tseem nyob rau ntawm nws qhov siab tshaj plaws raws li koj muaj kev txhawj xeeb nrog cov nyiaj solute yaj .
Vim li cas cov ntsiab lus ntawm cov ntawv tseeb yuav tsum tau kawm thiab tshuaj xyuas?
Cov ntsiab lus ntawm cov ntawv tseeb yog qhov tseem ceeb tshaj plaws hauv kev sau zaj dab neeg luv luv. Txhua lub ntsiab lus sawv cev qhov sib txawv piav qhia thiab kev txhais ntawm lub ntsiab lus uas tus sau xav xa tuaj rau tus nyeem . Vim li cas thiaj tseem ceeb kom paub cov ntsiab lus ntawm zaj dab neeg?
Dab tsi yog cov hauv qab no yog physicochemical zog?
Cov no suav nrog molecular hnyav, melting point, boiling point, vapor point, molecular polarity, Henry's theem faib, thiab extrinsic zog ntawm siab (P) thiab moles (n) . Yuav ua li cas yog lub zog ntawm lub cev? Physico-chemical zog yog tus yam ntxwv ntawm lub cev thiab tshuaj lom neeg ntawm ib yam khoom.
Yuav ua li cas cov txiv neej uas tsis muaj tshuaj tiv thaiv ib txwm tshuaj tsuag?
A: Ntau tus miv tsis tsuag tsuag Cov txiv neej muaj peev xwm ntau dua cov poj niam tshuaj tsuag, tab sis yog tias miv yog neutered ua ntej 6 hli, nws yuav luag tsis tshuaj. Yog hais tias tus txiv neej tsis zoo pib tshuaj tsuag, neutering nws yuav daws tau qhov teeb meem nyob rau hauv kwv yees li 95 feem pua ntawm cov mob .
