Colloidal systems nyob rau hauv peb lub neej

Colloidal tshuab - cov tshuab nyob rau hauv uas ib tug yeeb tshuaj yog nyob rau hauv lwm nyob rau hauv daim ntawv ntawm cov zoo hais. Feem ntau lawv kuj hu ua colloidally dispersed, txij thaum lub tsim ntawm cov tshuab - ib tug tshuaj txheej txheem ntawm cov hws thiab xaus ntawm ib tug yeeb tshuaj nyob rau hauv lwm, nyob rau lub hais ntawm solute yog nyob rau hauv qhov (Brownian) tsab ntawv tsa suab. Ib tug piv txwv colloidal dispersion tshuab tej zaum yuav emulsions, ncua, foams thiab txawv tej ntaub ntawv.

Colloidal tshuab rau tib neeg yog ib qho tseem ceeb. Nyob rau hauv qhov tseeb, tib neeg lub cev - ib tug ntau colloidal dispersion system. Vim hais tias lub cev yog yuav luag tag nrho cov tshuaj uas yaj nyob rau hauv ib lwm, thiab muaj nyob rau hauv qhov suab. Basic lom colloidal systems ntawm lub cev - cov ntshav thiab cov hlwb. Lub cell muaj ib tug nucleus, ribosomes, lysosomes, Golgi apparatus, EPR - ib yam khoom uas uniting mus rau hauv ib tug tag nrho ntawm tes, thiab hyaloplasm membrane.

Cov tub ntxhais yog ib tug colloidal nruab nrab, uas yog lub luag hauj lwm rau cov protein ntau biosynthesis thiab DNA stability. Lub membrane colloidal tshuaj lub luag hauj lwm rau lub elasticity ntawm daim nyias nyias thiab ua ib tug tiv thaiv muaj nuj nqi. Hyaloplasm - ib tug complex mix ntawm colloids, nyob rau hauv lub cell, lawv muab kev koom tes nyob rau hauv biochemical dab, raws li lawv ua tau rau lawv tus kheej rau koj tsiv los ntawm ib tug yeeb tshuaj mus rau lwm lub.

Ntshav tseem yog ib qho piv txwv lub cev nqaij, nyob rau hauv lub hauv paus yog ib tug colloidal dispersion system. Lub ntsiab ntawm cov ntshav, uas muaj xws li cov ntshav liab, qe ua ntshav khov thiab qe ntshav dawb - ib tug colloids, thiab cov ntshav ntshav - ib tug dispersion nruab nrab. Nyob rau hauv ntshav, tag nrho cov organic tshuaj yuav tsum tau hu ua colloid. Lub hauv paus ntawm cov ntshav yog cov dej, nws tsim ib tug dispersion nruab nrab nyob rau hauv uas organic povntawv ntawm ntshav yog: loj protein molecule, amino acid molecule, mono- thiab polysaccharides, thiab ntau lwm tus neeg.

Colloidal tshuab ua si ib qho tseem ceeb luag hauj lwm tsis tau tsuas yog nyob rau hauv lub neej ntawm tib neeg lub cev. Lawv kuj muaj zoo tswv yim tseem ceeb. Nyob rau lub hauv paus ntawm kev kawm colloid dispersed txheej txheem tshiab cov ntaub ntawv, yees ua ib tug ntau yam ntawm tshuaj dab tau tsim, uas yog siv feem nyob rau hauv lub ntau lawm, raws li tau zoo raws li rau kev kho mob ntawm cov dej (xws li dej).

Siv ib tug lom dej purification tshuab yog ua nce tseem ceeb heev, vim hais tias cov mov tshiab thiab dej haus yog txo. Dej kho mob tshuaj ua rau ntau muaj kuab paug.

Lom dej kev kho mob yog siv cov kev kab mob uas ua organic Cheebtsam ntawm dej. Zos ntawm cov kab mob tshwj xeeb daim ntawv peculiar colloidal systems nyob rau hauv daim ntawv ntawm cov zoo ncua. Thaum lub sij hawm xws tseem ceeb heev colonies kab mob nyob rau hauv nws cov khoom lim dej los ntawm kab mob.

Lom dej kev kho mob yog ib yam uas ob hom: clearance nyob rau hauv vivo, nyob rau hauv uas lub kab mob tau txais cov pa los ntawm cov ib puag ncig, thiab dag, nyob rau hauv uas lub kab mob yog ua tau hauj lwm nyob rau hauv ib tug kaw system, thiab cov pa nkag rau lawv los ntawm cov neeg kho tshuab aeration.
