NOJ COLLAGEN NTXIV RAU TXOJ KEV ZOO
Raws li txhua tus paub, kev xav tau kev tiv thaiv kev lauscollagenCov tshuaj ntxiv, tab sis peb txhua tus tsis quav ntsej tias collagen kuj tseem yuav tsum tau khaws cia. Yog tias koj tsis tuaj yeem khaws cia collagen, txawm tias koj ntxiv ntau ntxiv, nws yuav ploj mus. Collagen yuav tsum tau rov ua kom tiav thiab khaws cia tib lub sijhawm.
Tsis tas yuav piav qhia txog collagen yog dab tsi. Nws yog cov khoom tseem ceeb ntawm cov qauv tawv nqaij elastic. Muaj ntau hom collagen, xws li hom I, hom II, hom III, hom IV thiab lwm yam.

Muaj ob hom collagen uas tseem ceeb rau kev tiv thaiv kev laus. Hom III collagen muaj ntau nyob rau hauv daim tawv nqaij ntawm cov menyuam mos. Qhov lawv tsim yog cov fibrous net zoo heev. Yog vim li cas cov menyuam mos muaj daim tawv nqaij mos. Nrog rau kev nce hnub nyoog, hom III collagen maj mam hloov mus rau hom I collagen, tsim cov yam ntxwv ntawm daim tawv nqaij ntawm cov neeg laus. Yog li ntawd, qeeb qeeb kev hloov pauv ntawm hom III collagen mus rau hom I collagen hauv daim tawv nqaij tuaj yeem ua rau daim tawv nqaij mos thiab txo qhov zoo li ntawm daim tawv nqaij laus; Hom IV collagen yog ib qho tseem ceeb ntawm epidermal basement membrane, uas yog lub luag haujlwm rau kev txuas epidermis thiab dermis, thiab tseem ceeb rau kev tiv thaiv wrinkle.
Txawm li cas los xij, ib qho tseem ceeb: txoj haujlwm tseem ceeb tshaj plaws ntawm kev tiv thaiv kev laus yog los ntxiv hom I collagen. Qhov no yog vim hom I collagen tsim cov eosinophilic fibers loj, hu ua collagen fibers, uas tswj kev nruj ntawm daim tawv nqaij thiab dais kev nruj, thiab ua lub luag haujlwm tseem ceeb hauv kev nruj ntawm daim tawv nqaij thiab elasticity.
