Keratin yog ib hom protein ntau pom hauv koj cov plaub hau, tawv nqaij, thiab rau tes (1). Nws yog ib qho tseem ceeb tshwj xeeb rau kev tswj xyuas cov qauv ntawm koj cov tawv nqaij, txhawb kev kho qhov txhab, thiab ua kom koj cov plaub hau thiab rau tes noj qab nyob zoo thiab muaj zog (1).
Keratin yuav pom qhov twg?
Ib hom protein pom nyob rau epithelial cells, uas kab sab hauv thiab sab nraud ntawm lub cev. Keratin pab tsim cov ntaub so ntswg ntawm cov plaub hau, rau tes, thiab txheej txheej ntawm daim tawv nqaij. Lawv kuj pom muaj nyob rau ntawm cov hlwb hauv ob sab hauv ntawm lub cev, cov qog, thiab lwm qhov hauv lub cev.
Keratin nyob qhov twg nws pom thiab nws tsim li cas?
Keratins yog ib pawg ntawm cov tawv nqaij, cov proteins uas tsim cov txheej txheem ntawm cov hlwb hu ua keratinocytes uas ua rau ntawm daim tawv nqaij, plaub hau, thiab rau tes. Keratin 1 yog tsim tawm hauv keratinocytes nyob rau hauv txheej txheej ntawm daim tawv nqaij (cov epidermis), suav nrog cov tawv nqaij ntawm ob txhais tes thiab ob txhais taw.
Keratin rho tawm qhov twg?
Kev lig kev cai, keratin tau muab rho tawm los ntawm tsiaj tawv nqaij nrog rau cov ntaub plaub, plaub, hooves thiab horns tshwj xeeb tshaj yog siv rau hauv kev lag luam tshuaj pleev ib ce [1, 20, 21].
Keratin ua li cas?
Cov plaub hau
Cov plaub hau yog tsim los ntawm 95% keratin, fibrous, helicoidal protein (zoo li lub helix) uas tsim ib feem ntawm daim tawv nqaij thiab tag nrho nws cov appendages (lub cev plaub hau, rau tes, thiab lwm yam).). Keratin yog synthesized los ntawm keratinocytes thiab yog insoluble nyob rau hauv dej, yog li xyuas kom impermeability thiab tiv thaiv cov plaub hau.

Vim li cas qhov pom kev pom qhov tseem ceeb?
Enlightened despots tau tuav tseg tias muaj hwj chim muaj hwj chim emanated tsis yog los ntawm txoj cai los saum ntuj los tab sis los ntawm kev cog lus ntawm kev sib raug zoo uas ib tus neeg tau tso siab rau lub hwj chim los tswj hwm ntawm lwm lub tseem fwv Nyob rau hauv qhov tseeb, Cov huab tais ntawm enlightened absolutism enlightened absolutism Enlightened absolutism (tseem hu ua enlightened despotism) yog hais txog kev coj ua thiab kev cai ntawm European absolute monarchs
Qhov pom kev tsis pom kev txhais li cas?
Kev pom kev tsis pom kev yog ib lo lus kws txawj siv los piav qhia txhua yam tsis pom kev, txawm tias nws yog ib tus neeg tsis pom kev lossis ib tus neeg uas tsis pom kev ib nrab. Qee tus neeg dig muag tag, tiam sis muaj coob leej lwm tus muaj qhov hu ua qhov muag tsis pom kev raug cai .
Keratin pom nyob qhov twg hauv daim tawv nqaij?
Ib hom protein pom nyob rau epithelial cells, uas kab sab hauv thiab sab nraud ntawm lub cev. Keratin pab tsim cov ntaub so ntswg ntawm cov plaub hau, rau tes, thiab txheej txheej ntawm daim tawv nqaij. Lawv kuj pom muaj nyob rau ntawm cov hlwb hauv ob sab hauv ntawm lub cev, cov qog, thiab lwm qhov hauv lub cev .
Puas pom keratin?
Ib hom protein pom nyob rau epithelial cells, uas kab sab hauv thiab sab nraud ntawm lub cev. Keratin pab tsim cov ntaub so ntswg ntawm cov plaub hau, rau tes, thiab txheej txheej ntawm daim tawv nqaij. Lawv kuj pom muaj nyob rau ntawm cov hlwb hauv ob sab hauv ntawm lub cev, cov qog, thiab lwm qhov hauv lub cev .
Dab tsi yog qhov txawv ntawm kev pom tsis pom thiab pom tsis pom ntau dua?
Kev muaj peev xwm tawm tsam yam tsis muaj qhov kawg ntawm kev sau ntawv vs kev tuaj yeem cuam tshuam rau lwm tus neeg kuj yog qhov sib txawv. Qhov tseem ceeb Invisibility yog "qhov tseeb nrhiav / nkaum / mus ncig tsis pom" qhov twg Qhov Kev Pom Zoo Tshaj Plaws yog ntau ntawm kev sib ntaus sib tua Puas pom qhov tsis pom kev ua haujlwm ntawm kev pom tsis pom ntau dua?
