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. Ntau N-txuas cov glycoproteins thaum kawg dhau los ua ib feem ntawm cov cell membrane lossis zais los ntawm lub cell.
Ib sab ntawm 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.
Zoo sib xws, dab tsi yog qee qhov piv txwv ntawm glycoproteins? Piv txwv . Ib qho 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 rau mucins muab lawv muaj peev xwm tuav dej ntau thiab tseem ua rau lawv tiv taus cov proteolysis los ntawm cov zom zaub mov.
Cov lus nug tseem yog, qhov sib xyaw glycoprotein tshwm sim nyob qhov twg?
Glycoprotein synthesis tshwm sim hauv ob lub cev sib luag xws li endoplasmic reticulum thiab Golgi apparatus. Lub hauv paus ntawm cov carbohydrates yog txuas rau cov protein ob qho tib si txhais ua lus thiab tom qab txhais lus. Ribosome coj tus mRNA uas yog tus lej rau cov protein txuas rau endoplasmic reticulum.
Cov carbohydrates feem ntau txuas nrog cov protein kom tsim tau glycoproteins li cas?
Cov carbohydrates ua tau txuas rau cov protein kom tsim tau glycoproteins . Hauv cov glycoproteins , cov carbohydrates cov saw yog txuas nrog rau nitrogen atom nyob rau sab saw ntawm asparagine (N-txuas) lossis rau cov pa oxygen hauv cov saw sab lossis serine lossis threonine (O-linkage.)

Tus txha nqaj qaum tau tsim li cas?
Txhua lub paj hlwb tau tsim los ntawm kev sib txuas ua ke ntawm cov hlab ntsha los ntawm dorsal thiab ventral keeb kwm ntawm tus txha caj qaum. Cov hauv paus hauv qab nqa nqa cov kev xav zoo ib yam axons, thaum lub hauv paus cov hauv paus nqa lub cev muaj zog zoo sib xws
Muaj pes tsawg tus Spermatids tau tsim los ntawm thawj tus Spermatocyte?
Plaub spermatids
Qhov feem pua ntawm cov ntshav tau tsim los ntawm cov khoom tsim?
Cov qe ntshav no (uas tseem hu ua corpuscles lossis 'tsim cov ntsiab lus') suav nrog erythrocytes (cov qe ntshav liab, RBCs), leukocytes (cov qe ntshav dawb), thiab thrombocytes (platelets). Los ntawm qhov ntim, cov qe ntshav liab muaj li ntawm 45% ntawm cov ntshav tag nrho, cov ntshav plasma txog 54.3%, thiab cov qe dawb txog 0.7%
Thaum tus kws kho mob tau tso cai tso cai ntau npaum li cas yuav tsum muaj kev sib ntsib tim ntsej tim muag tshwm sim ntawm tus kws kho mob thiab cov kws kho mob qib siab uas tau sau npe rau tus nais maum?
Txawm li cas los xij, yog tias APRN lossis PA tau nyob hauv daim ntawv pom zoo tso cai nrog kws saib xyuas kws kho mob tsawg kawg tsib ntawm xya xyoo dhau los, cov rooj sib tham tim ntsej tim muag yuav tsum tshwm sim tsawg kawg ib hlis txog rau thawj hnub ntawm hnub uas tau pom zoo kos npe
Koj ua li cas thiaj tsim tau tus cwj pwm zoo?
Txhim kho tus cwj pwm zoo Mloog koj cov lus sib tham sab hauv. Thaum ntsib kev xav tsis zoo, tig rov los ua kom muaj kev xav zoo. Sib tham hauv ib puag ncig zoo thiab nrog cov neeg zoo. Tuaj pab dawb. Tau txais kev txaus siab ntawm tej yam yooj yim hauv lub neej. Tso cai rau koj tus kheej kom hlub
