Cov slime txheej yog ib qho yooj yim tshem tawm, diffuse, unorganized txheej ntawm extracellular khoom uas nyob ib ncig ntawm cov kab mob cell. Nws feem ntau yog tsim los ntawm polysaccharidesthiab nws yuav ua haujlwm rau cov khoom noj khoom haus, pab hauv cell motility, khi hlwb ua ke los yog ua raws li qhov chaw du.
Dab tsi yog hauv qab txheej slime?
Ib txheej slime nyob rau hauv cov kab mob yog ib qho yooj yim tshem tau (xws li los ntawm centrifugation), unorganized txheej ntawm extracellular khoom uas nyob ib ncig ntawm cov kab mob hlwb. Tshwj xeeb, qhov no muaj feem ntau ntawm exopolysaccharides, glycoproteins, thiab glycolipids. Yog li ntawd, cov slime txheej yog suav tias yog ib tug subset ntawm glycocalyx.
Qhov txawv ntawm glycocalyx thiab slime txheej yog dab tsi?
Nyob rau hauv cov kab mob thiab xwm
Glycocalyx muaj nyob rau hauv cov kab mob xws li tshuaj ntsiav lossis txheej slime. … Qhov txawv ntawm ib lub tshuaj ntsiav thiab ib txheej slime yog uas nyob rau hauv ib lub capsule polysaccharides khov kho rau ntawm phab ntsa ntawm tes, thaum nyob rau hauv ib txheej slime, cov glycoproteins yog xoob txuas mus rau phab ntsa ntawm tes.
YGlycocalyces yog dab tsi?
Glycocalyx yog tsim los ntawm glycosaminoglycans, proteoglycans thiab lwm yam glycoproteins bearing acidic oligosaccharides thiab terminal sialic acids. Feem ntau cov glycocalyx txuam nrog cov proteins yog transmembrane uas tuaj yeem txuas rau cytoskeleton.
slime txheej lossis tshuaj ntsiav yog dab tsi?
Ntau cov kab mob hauv lub cev zais qee cov khoom siv ntxiv rau hauv daim ntawvcapsule los yog slime txheej. Ib txheej slime yog xoob txuam nrog cov kab mob thiab tuaj yeem ntxuav tau yooj yim, thaum lub tshuaj ntsiav yog txuas nrog nruj rau cov kab mob thiab muaj cov ciam teb tseeb.
