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.
