Ukuqaliswa kohlobo lwe-II Collagen
Yintoni uhlobo II collagen?
Uhlobo lwe-II i-collagen yiprotheni ye-fibrillar eyenziwe ngamatyathanga ama-3 amade e-amino acids eyenza inethiwekhi epakishwe ngokuqinileyo yeefibrils kunye nemicu. Yeyona nxalenye iphambili ye-cartilage emzimbeni. Iqukethe ubunzima obomileyo kunye ne-collagens.
Uhlobo lwe-II i-collagen yinto enika i-cartilage amandla ayo okuqina kunye no-elasticity, ngaloo ndlela ivumela ukuba ixhase amalungu. Inceda kwinkqubo yokubopha ngoncedo lwe-fibronectin kunye nezinye ii-collagens.
Uthini umahluko phakathi kohlobo lwe-II kunye nohlobo lwe-collagen ye-I?
Phezulu zibonakala ziyafana, nganye kuzo iyiheliksi kathathu, oko kukuthi, yenziwe ngamatyathanga amathathu amade ee-amino acid. Nangona kunjalo, kwinqanaba leemolekyuli kukho umahluko obalulekileyo.
Chwetheza i-collagen: Amakhonkco amabini kulawa mathathu ayafana.
Uhlobo II collagen: Omathathu amatyathanga ayafana.
Uhlobo I Collagen ifumaneka ikakhulu emathanjeni naselusu. Ngelixa uhlobo lwe-II collagen lufumaneka kuphela kwi-cartilage.
Ziziphi iingenelo ezidlala uhlobo lwe-II collagen emzimbeni?
Njengoko sibonile, uhlobo lwe-II collagen luyinxalenye enkulu yezicubu ze-cartilage. Ngoko ukuze uyiqonde ngokwenene indima eyidlalayo, umntu kufuneka ajonge umsebenzi wentlaka emzimbeni.
ICartilage sisihlunu esiqinileyo kodwa esithambileyo. Kukho iintlobo ezahlukeneyo ze-cartilage emzimbeni, nganye inomsebenzi othile. I-cartilage efunyenwe kumalungu inemisebenzi emininzi, efana
- ukudibanisa amathambo
- ukuvumela izicubu ukuba zithwale uxinzelelo lomatshini
- ukufunxa ukothuka
- ukuvumela amathambo adibeneyo ukuba ahambe ngaphandle kokukhuhlana
I-Cartilage yenziwe ngee-chondrocytes eziziiseli ezikhethekileyo ezenza into eyaziwa ngokuba yi-'extracellular matrix' equka i-proteoglycan, i-elastin fibers kunye nohlobo lwe-II collagen fibers.
Uhlobo lwe-II lwe-collagen fibers luyinto ephambili ye-collagenous efumaneka kwi-cartilage. Badlala indima ebaluleke kakhulu. Benza uthungelwano lweefibrils ezinceda ukudibanisa iproteoglycan kunye ne-elastin fibers ibe yinyama eqinile, kodwa eguquguqukayo.
