Ukuqaliswa kohlobo lwe-II Collagen

Yintoni uhlobo II collagen?

Uhlobo IIicollagenyiprotheni ye-fibrillar eyenziwe ngamatyathanga ama-3 amade e-amino acids enza inethiwekhi epakishwe ngokuqinileyo yeefibrils kunye neefiber.Yeyona nxalenye iphambili ye-cartilage emzimbeni.Iqukethe ubunzima obomileyo kwayeii-collagens.

Uhlobo IIicollagenyeyona nto inika intlala amandla ayo okuqina kunye nokunwebeka, nto leyo eyenza ukuba ikwazi ukuxhasa amalungu.Inceda kwinkqubo yokubopha ngoncedo lwefibronectin kunye nezinyeii-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.

ICartilage yenziwe ngeechondrocytes eziziiseli ezikhethekileyo ezenza into eyaziwa ngokuba yi-'extracellular matrix' equka iproteoglycan, i-elastin fibers kunye nohlobo lwe-II.icollagenimicu.

Uhlobo IIicollageniifibers yeyona nto iphambili yecollagenous efumaneka kwicartilage.Badlala indima ebaluleke kakhulu.Benza uthungelwano lweefibrils ezinceda ukudibanisa iproteoglycan kunye ne-elastin fibers ibe yinyama eqinile, kodwa eguquguqukayo.
