Wedzera Kolajeni Nenzira Yakarurama
Sekuziva kunoita munhu wese, zvinodiwa kuti munhu asachemberakolajenizvinowedzerwa, asi tese tinofuratira kuti collagen inofanirawo kuchengetedzwa. Kana usingakwanise kuchengetedza collagen, kunyangwe ukawedzera, icharasika. Collagen inofanira kuzadzwazve uye kuchengetedzwa panguva imwe chete.
Hazvidikanwi kutsanangura kuti collagen chii. Ndiyo inonyanya kukosha pakugadzirwa kweganda. Kune mhando dzakawanda dzecollagen, dzakadai serudzi rwekutanga, rudzi rwechipiri, rudzi rwechitatu, rudzi rwechina nezvimwewo. Pakati padzo, huwandu hwese hwe collagen yerudzi rwekutanga muganda revakuru ndihwo hwakanyanya, huchiumba 85% ye collagen yemunhu.
Kune mamwe marudzi maviri ecollagen akakosha pakudzivirira kukwegura. Kolajeni yerudzi rwechitatu ine ganda rakawanda muganda revacheche. Zvavanoumba inet ine fibrous. Ndosaka vacheche vaine ganda rakapfava. Nekukura kwezera, kolajeni yerudzi rwechitatu inochinja zvishoma nezvishoma kuita kolajeni yerudzi rwekutanga, zvichigadzira hunhu hweganda hwevanhu vakuru. Nokudaro, kunonoka kuchinja kubva kukolajeni yerudzi rwechitatu kuenda kukolajeni yerudzi rwekutanga muganda kunogona kuwedzera kupfava kweganda uye kuderedza kukwegura kweganda; Kolajeni yerudzi rwechina chikamu chakakosha che epidermal basement membrane, iyo ine basa rekubatanidza epidermis nedermis, uye yakakoshawo pakudzivirira makunya.
Zvisinei, chinhu chikuru: basa guru rekudzivirira kukwegura nderekuwedzera collagen yerudzi rwekutanga. Izvi zvinodaro nekuti collagen yerudzi rwekutanga inoumba mafiber makuru eosinophilic, anonzi mafiber ecollagen, ayo anochengetedza kushushikana kweganda uye anobereka kushushikana, uye anoita basa guru mukusimba kweganda uye kusimba kwaro.
Kolajeni yerudzi rweI ine cheni nhatu refu dzekolajeni dzakaita sema helical, izvo zvinoita kuti chimiro chayo chigadzikane zvakanyanya. Uyezve, inogona kubata chimiro chekolajeni zvakasimba. Network yekolajeni fiber yakarukwa nekolajeni yerudzi rweI yakasimba uye inochinjika, saka inogona kutsigira chimiro chekolajeni.
Zvinogona kutaurwa kuti kuwedzera collagen type I kunochengetedza zvakananga network ye collagen fiber muganda uye ndiyo kiyi yekuchengetedza ganda richiri diki.
