ENGEZA I-COLLAGEN NGENDLELA EFANELE
Njengoba wonke umuntu azi, izidingo zokulwa nokugugai-collagenisithasiselo, kodwa sonke siyakushalazela ukuthi i-collagen nayo idinga ukugcinwa. Uma ungakwazi ukugcina i-collagen, noma ngabe ungeza okwengeziwe, izolahleka. I-Collagen kufanele igcwaliswe futhi igcinwe ngesikhathi esifanayo.
Akudingeki ukuchaza ukuthi iyini i-collagen. Iyona eyinhloko yesakhiwo sesikhumba esinwebekayo. Kunezinhlobo eziningi ze-collagen, njengohlobo I, uhlobo II, uhlobo III, uhlobo IV njalo njalo. Phakathi kwazo, okuqukethwe yi-collagen yohlobo I esikhumbeni somuntu omdala kukhulu kakhulu, okwenza u-85% we-collagen yomuntu.
Kunezinye izinhlobo ezimbili ze-collagen ezibalulekile ekulweni nokuguga. I-collagen yohlobo lwesithathu iphezulu esikhumbeni sezingane. Lokho ezikwakhayo inethi encane ene-fibrous. Yingakho izingane zinesikhumba esibucayi. Njengoba iminyaka ikhula, i-collagen yohlobo lwesithathu ishintsha kancane kancane ibe yi-collagen yohlobo lwe-I, yakha izici zesikhumba zabantu abadala. Ngakho-ke, ukwehlisa ijubane lokushintsha kusuka ku-collagen yohlobo lwe-III kuya ku-collagen yohlobo lwe-I esikhumbeni kungathuthukisa ubumnene besikhumba futhi kunciphise ukubonakala kobudala besikhumba; I-collagen yohlobo lwe-IV iyisici esibalulekile se-epidermal basement membrane, ebhekene nokuxhumanisa i-epidermis ne-dermis, futhi ibalulekile nasekulweni nemibimbi.
Kodwa-ke, iphuzu elibalulekile: umsebenzi obaluleke kakhulu wokulwa nokuguga ukwengeza i-collagen yohlobo I. Lokhu kungenxa yokuthi i-collagen yohlobo I yakha imicu emikhulu ye-eosinophilic, ebizwa ngokuthi imicu ye-collagen, egcina ukucindezeleka kwesikhumba futhi ithwale ukucindezeleka, futhi idlala indima ebalulekile ekuqineni kwesikhumba nasekuqineni.
I-collagen yohlobo lwe-I inamaketanga amathathu amade kakhulu e-collagen helical, okwenza isakhiwo sayo sizinze kakhulu. Ngaphezu kwalokho, ingabamba isakhiwo se-collagen ngokuqinile. Inethiwekhi ye-collagen fiber elukiwe yi-collagen yohlobo lwe-I inamandla futhi iyanwebeka, ngakho ingasekela isakhiwo se-collagen.
Kungashiwo ukuthi ukwengeza uhlobo lwe-collagen I kugcina ngqo inethiwekhi ye-collagen fiber esikhumbeni futhi kuyisihluthulelo sokugcina isikhumba sisesisha.
