1) Collagen plays lub luag haujlwm tseem ceeb hauv cov txheej txheem kho qhov txhab thiab caws pliav.Nws tuaj yeem tsis tsuas yog ua lub luag haujlwm rau cov ntaub so ntswg elastic thiab cov tshuaj adhesion, tab sis kuj txhawb kev loj hlob ntawm tes, sib txawv, cov ntaub so ntswg sib txawv thiab kev loj hlob, thiab cov ntaub so ntswg sib txuas.Kev sib txawv thiab kev loj hlob, Nws tuaj yeem txhawb nqa capillary angiogenesis, induce chemotaxis ntawm monocytes thiab fibroblasts, thiab noj thiab tswj cov ntaub so ntswg granulation.Raws li cov lus ceeb toom, kev siv cov collagen hauv kev kho mob ntawm daim tawv nqaij ulcers tshwm sim los ntawm kev sib txawv ua rau muaj kev cuam tshuam zoo, uas tuaj yeem ua rau lub qhov txhab thiab qhov tob ntawm epithelialization, uas yog qhov tsim nyog rau kev tsim cov ntaub so ntswg granulation.(2) 70% -80% ntawm cov organic teeb meem hauv cov pob txha yog collagen.Thaum cov pob txha tsim, txaus collagen fibers yuav tsum xub muab synthesized los tsim lub moj khaum ntawm cov pob txha.Yog li ntawd, qee cov neeg hu ua collagen cov pob txha.Collagen fibers muaj zog toughness thiab elasticity.Yog hais tias cov pob txha ntev yog piv rau cov cement kem, ces collagen fibers yog cov hlau ncej ntawm lub kem, thiab qhov tsis muaj collagen zoo li kev siv cov hlau tsis zoo hauv cov tsev, thiab qhov txaus ntshai ntawm kev tawg tsuas yog nyob rau yav tsaus ntuj.(3) Cov nyhuv ntawm collagen ntawm lub mis txhim kho tau ntev tau paub rau tib neeg.Lub mis yog tsim los ntawm cov ntaub so ntswg thiab cov ntaub so ntswg adipose, thaum lub mis siab, ncaj thiab plump loj nyob ntawm kev txhawb nqa ntawm cov ntaub so ntswg.Collagen yog qhov tseem ceeb ntawm cov ntaub so ntswg sib txuas."Collagen feem ntau cuam tshuam nrog polysaccharide protein nyob rau hauv cov ntaub so ntswg sib txuas. Nws yog intertwined rau hauv cov qauv mesh los ua kom muaj zog txhua yam, uas yog cov khoom siv hauv paus rau kev txhawb nqa tib neeg lub cev nkhaus thiab xav txog lub ntsej muag ncaj."(4) Collagen hu ua "cov pob txha hauv cov pob txha, cov tawv nqaij hauv cov tawv nqaij, thiab cov nqaij hauv cov nqaij"., tuaj yeem hais tias yog lub zog txhawb nqa ntawm dermis, thiab nws cov nyhuv ntawm daim tawv nqaij yog qhov tseeb.Kev tiv thaiv thiab zoo elasticity: qis txheej ntawm cov epidermis, uas nyob rau feem ntau ntawm cov qauv yog dermis txheej, nrog ib tug tuab ntawm txog 2 hli, thiab yuav muab faib ua peb txheej, uas yog lub papillary txheej, sub-papillary txheej thiab cov txheej txheem reticular, feem ntau yog tsim los ntawm cov proteins., Qhov no ib feem ntawm cov protein yog tsim los ntawm collagen thiab elastin (elastin), lwm tus yog paj hlwb, capillaries, hws thiab sebaceous qog, lymphatic hlab ntsha thiab cov hauv paus plaub hau.70% ntawm daim tawv nqaij yog tsim los ntawm collagen.Cov tawv nqaij zoo li lub tes tsho loj nruj nreem qhwv txhua qhov ntawm lub cev, thiab thaj chaw saum npoo yog loj heev.Thaum tib neeg cov ceg tawv txav mus, cov collagen hauv daim tawv nqaij ua haujlwm, kom cov tawv nqaij muaj kev tiv thaiv.Elasticity thiab nruj
