Ib qho inverse linear kev sib raug zoo tau pom ntawm kub thiab cov muab faib coefficient . CONCLUSION: Nyob rau hauv ib tug ntau yam ntawm kub , cov muab faib coefficient isoflurane thiab sevoflurane txo qis raws li qhov kub nce. Sevoflurane qhia tau hais tias muaj kev solubility siab hauv Oxygent (TM) piv rau isoflurane.

Tsis tas li ntawd, koj puas xav kom qhov sib faib coefficient sib txawv nrog qhov kub thiab txias?

Cov muab faib coefficient ntawm cov protein me me thiab hydrophilic xws li lysozyme thiab chymotrypsinogen-A tsuas yog cuam tshuam me ntsis los ntawm kev hloov pauv hauv kub , thaum lub muab faib coefficient ntawm qhov loj thiab ntau hydrophobic proteins xws li albumin thiab catalase muaj zog cuam tshuam los ntawm kev hloov hauv kub.

Vim li cas octanol siv los ntsuas qhov sib faib coefficient? Octanol - dej muab faib coefficient (Kow) yog ib qho tseem ceeb heev uas muaj ntau yam kev siv ib puag ncig, qhov twg nws yog siv raws li tus yam ntxwv tseem ceeb parameter vim nws sawv cev rau a ntsuas Kev xav ntawm ib qho kev sib xyaw kom txav los ntawm cov theem aqueous mus rau lipids.

Tsis tas li ntawd, qhov sib faib coefficient qhia koj li cas?

Nyob rau hauv lub cev sciences, a muab faib coefficient (P) lossis kev faib tawm coefficient (D) yog qhov sib piv ntawm cov concentrations ntawm ib qho compound nyob rau hauv ib tug sib tov ntawm ob immiscible solvents ntawm equilibrium. Li no lub muab faib coefficient ntsuas seb hydrophilic ("dej-hlub") los yog hydrophobic ("dej-ntshai") cov tshuaj yog tshuaj.

Dab tsi cuam tshuam rau kev faib coefficient?

Qhov ntau dua qhov solubility ntawm ib yam khoom, nws siab dua muab faib coefficient , thiab siab dua muab faib coefficient , qhov siab dua qhov permeability ntawm daim nyias nyias rau cov khoom tshwj xeeb. Piv txwv li, dej solubility ntawm hydroxyl, carboxyl, thiab amino pawg txo lawv cov solubility …
