Glycoproteins yog cov protein uas muaj suab thaj txuas rau lawv. Lawv ua Muaj ntau txoj haujlwm tseem ceeb rau lub cev, xws li pab lub cev tiv thaiv kab mob, plab zom mov, thiab kev ua me nyuam.
Tsis tas li kom paub yog, glycoprotein ua dab tsi hauv cov cell membrane?
Glycoproteins tau pom nyob rau saum npoo ntawm lipid bilayer ntawm cell daim nyias nyias . Lawv qhov xwm txheej hydrophilic tso cai rau lawv ua haujlwm hauv ib puag ncig aqueous, uas lawv ua hauv ntawm tes - ntawm tes paub thiab khi ntawm lwm cov molecules.
Tsis tas li ntawd, kev ua haujlwm ntawm glycolipid yog dab tsi? Glycolipids yog lipids nrog cov carbohydrate txuas los ntawm glycosidic (covalent) daim ntawv cog lus. Lawv lub luag haujlwm yog tswj hwm kev ruaj ntseg ntawm ntawm tes daim nyias nyias thiab ua kom yooj yim rau kev lees paub ntawm tes, uas yog qhov tseem ceeb rau kev tiv thaiv kab mob thiab hauv kev sib txuas uas tso cai rau cov cell txuas mus rau ib leeg los tsim cov ntaub so ntswg.
Qhov thib ob, cov piv txwv ntawm glycoproteins yog dab tsi?
Piv txwv . Ib piv txwv ntawm glycoproteins pom nyob rau hauv lub cev yog mucins, uas yog zais hauv cov hnoos qeev ntawm txoj kev ua pa thiab zom zaub mov. Cov suab thaj thaum txuas nrog mucins muab lawv lub peev xwm tuav dej ntau thiab tseem ua rau lawv tiv taus proteolysis los ntawm digestive enzymes.
Yuav tsim cov glycoproteins li cas?
Glycoprotein hmoov . Glycoproteins yog cov proteins uas muaj covalently txuas qab zib residues. Lub ntsiab ntawm cov protein glycoprotein ua tau sib sau ua ke nyob rau saum npoo ntawm qhov ntxhib endoplasmic reticulum los ntawm qhov sib ntxiv ntawm cov amino acids, tsim cov kab tawm polymer ntawm cov amino acids hu ua polypeptide.
Pom zoo:
Cerebrum yog dab tsi thiab nws ua dab tsi?
Cerebrum: yog qhov loj tshaj plaws ntawm lub paj hlwb thiab suav nrog ntawm sab xis thiab sab laug hemispheres. Nws ua haujlwm zoo dua qub xws li txhais lus kov, pom kev thiab hnov lus, nrog rau kev hais lus, kev xav, kev xav, kev kawm, thiab kev tswj kom zoo. Cerebellum: nyob hauv qab lub paj hlwb
Dab tsi yog glycoprotein dab tsi yog ib qho ntawm kev siv glycoproteins?
Glycoproteins yog cov protein uas muaj cov oligosaccharide saw (glycans) covalently txuas nrog cov amino acid sab-saw. Glycoproteins kuj tseem yog ib qho tseem ceeb ua ke ntawm cov protein, uas lawv ua lub luag haujlwm hauv kev sib cuam tshuam ntawm tes -cell
Dab tsi ua rau ib yam dab tsi?
Primates muaj lub hlwb loj (txheeb ze rau lub cev me me) piv rau lwm hom tsiaj, nrog rau kev vam khom ntau ntxiv ntawm kev pom kev pom ntawm tus nqi ntawm kev hnov ntxhiab tsw, uas yog lub hauv paus kev nkag siab ntawm cov tsiaj feem ntau. Tsuas yog rau apes thiab tib neeg, cov tsiaj muaj tails. Cov tsiaj txhu feem ntau tseem muaj cov ntiv tes thim rov qab
Dab tsi yog cov khoom siv hauv lub cev zom zaub mov thiab lawv lub luag haujlwm yog dab tsi?
Cov khoom siv hauv lub cev zom zaub mov suav nrog cov hniav, tus nplaig, cov qog ua kua qaub, daim siab, lub zais zis, thiab txiav txiav. Txhawm rau ua tiav lub hom phiaj ntawm kev muab lub zog thiab khoom noj khoom haus rau lub cev, rau lub luag haujlwm tseem ceeb nyob hauv cov txheej txheem zom zaub mov: nqos. Kev zais
Tus glycoprotein tsim tau li cas?
Cov protein tivthaiv ntawm glycoprotein tau sib sau ua ke ntawm qhov ntxhib endoplasmic reticulum los ntawm qhov sib ntxiv ntawm cov amino acids, tsim cov kab tawm polymer ntawm cov amino acids hu ua polypeptide. Ntau N-txuas glycoproteins thaum kawg dhau los ua ib feem ntawm cov cell membrane lossis zais los ntawm lub cell
