Glycoproteins cov yog cov protein uas muaj cov oligosaccharide saw (glycans) covalently txuas rau cov amino acid sab-saw. Glycoproteins kuj tseem yog ib qho tseem ceeb ntawm cov protein sib cais, uas lawv ua lub luag haujlwm hauv kev sib cuam tshuam ntawm tes -cell.
Xav txog qhov no, lub hom phiaj ntawm glycoproteins yog dab tsi?
Glycoprotein hmoov Piv txwv thiab Kev Ua Haujlwm Glycoproteins muaj nuj nqi hauv tus qauv, kev tsim dua tshiab, kev tiv thaiv kab mob, cov tshuaj hormones, thiab kev tiv thaiv ntawm tes thiab kab mob. Xovtooj ntawm tes cov glycoproteins tseem yog qhov tseem ceeb rau kev sib txuas ntawm cov hlwb thiab cov protein (piv txwv li, collagen) ntxiv dag zog thiab ruaj khov rau cov nqaij.
Tom qab ntawd, lo lus nug yog, yuav tsim cov glycoproteins li cas? Glycoprotein hmoov . Glycoproteins yog cov protein uas muaj covalently txuas cov piam thaj seem. Qhov sib xyaw ntawm cov protein glycoprotein cov 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.
Ib yam nkaus, ua li cas glycoproteins ua haujlwm?
Glycoproteins cov thiab Glycolipids [kho kom raug] Lipid thiab cov protein ntawm lub cell membrane nto feem ntau muaj cov kab carbohydrates luv luv uas tawm los ntawm cov xovtooj ntawm tes, hu ua glycolipids thiab cov glycoproteins . Lawv tsim hydrogen sib txuas nrog cov dej molecules puag ncig ntawm tes thiab yog li pab rau ruaj khov cov qauv membrane.
Dab tsi yog glycolipids siv rau?
Glycolipids yog cov lipids nrog cov carbohydrate txuas los ntawm kev sib txuas glycosidic lossis covalent bonded. Lawv tau pom nyob rau sab nrauv ntawm cov xovtooj ntawm tes uas nws ua lub luag haujlwm txhim kho kom ruaj ntseg daim nyias nyias, thiab tseem pab txhawb kev sib txuas lus ntawm tes ntawm tes ua tus txais khoom, thauj tog rau nkoj rau cov protein.

Ib qho piv txwv ntawm kev xav txog kev xav txog kev xav yog dab tsi?
5 Kev Cuam Tshuam Tus Kheej (thiab Social Identity) Cov Qauv Piv Txwv suav nrog pab pawg kis las, kev ntseeg, haiv neeg, kev ua haujlwm, kev nyiam sib deev, haiv neeg, thiab poj niam txiv neej. Social Identity txoj kev xav hais txog txoj hauv kev uas social identities cuam tshuam rau tib neeg tus cwj pwm thiab kev coj cwj pwm ntawm lawv pawg neeg thiab pawg neeg sab nrauv
Kev sib raug zoo ntawm kev loj hlob ntawm tes thiab kev tsim tawm ntawm tes yog dab tsi?
Thaum lub sij hawm Binary fission thiab mitosis theej tawm cov DNA cov ntsiab lus ntawm kev tsim cov niam txiv ntawm tes tau muab cais ua ob qhov sib npaug sib luag uas yog lub hom phiaj kom xaus rau hauv ob tus ntxhais ntxhais. Ib feem kawg ntawm cov txheej txheem ntawm kev tsim cov cell yog faib cell, thaum tus ntxhais lub cev lub cev sib cais los ntawm niam txiv ntawm tes
Cov kab mob sib koom ua ke twg yog tus cwj pwm los ntawm kev sib koom ua ke ntawm kev txav mus los thiab kev sib koom ua ke ntawm qhov hnyav ntawm cov pob qij txha uas feem ntau yog relieved los ntawm so?
Osteoarthritis feem ntau cuam tshuam rau txhais tes, qis nraub qaum, caj dab, thiab hnyav sib koom tes xws li hauv caug, lub duav, thiab ko taw
Dab tsi yuav tsum tau xav txog thaum tsiv ntawm ib qho chaw zaum mus rau ib qho chaw sawv ntsug?
Tsiv Los Ntawm Zaum Rau Sawv Cev Yog tias koj nyob hauv lub rooj zaum nrog caj npab, scoot rau pem hauv ntej kom txog thaum koj nyob ntawm ntug ntawm lub rooj zaum. Coj koj txhais taw mus rau ntawm lub rooj zaum. Ces sawv ntsug. Yog tias koj lub rooj zaum tsis muaj caj npab, tso koj tus kheej li saum toj no. Muab koj txhais tes tso rau ntawm lub rooj zaum ntawm koj tus ncej puab thiab thawb. Khaws koj nraub qaum kom ncaj li koj ua tau
Ib qho piv txwv ntawm kev loj hlob ntawm kev xav yog dab tsi?
Piv txwv ntawm kev nkag siab kev xav thiab kev tswj tus kheej suav nrog: txheeb xyuas qhov tseeb ntawm tus kheej hauv lawv tus kheej thiab lwm tus; tswj kev xav muaj zog xws li kev zoo siab, npau taws, ntxhov siab thiab ntxhov siab; thiab. yog kev nkag siab thiab nkag siab lwm tus txoj kev xav
