Type II collagen ndi chiyani?
Mtundu IIkolajenindi mapuloteni opangidwa ndi 3 maunyolo aatali a amino acid omwe amapanga maukonde odzaza kwambiri a fibrils ndi ulusi.Ndilo gawo lalikulu la cartilage m'thupi.Amakhala youma kulemera ndicollagens.
Mtundu IIkolajenindi zomwe zimapangitsa kuti chichereŵechereŵe chikhale cholimba komanso kuti chikhale chotanuka, motero chimathandiza kuti mafupawo azilumikizana.Zimathandizira pakumanga mothandizidwa ndi fibronectin ndi zinacollagens.
Kodi pali kusiyana kotani pakati pa Type II ndi Type I collagen?
Pamwamba zimawoneka zofanana, iliyonse ili ndi helix katatu ie yopangidwa ndi maunyolo atatu aatali a amino acid.Komabe, pamlingo wa maselo pali kusiyana kwakukulu.
Type I collagen: Awiri mwa maunyolo atatu ali ofanana.
Type II collagen: Maunyolo onse atatu ndi ofanana.
Type ICollagenamapezeka makamaka m'mafupa ndi khungu.Pomwe mtundu IIkolajenichimapezeka kokha mu chichereŵechereŵe.
Ndi phindu lanji lomwe limapanga mtundu wa IIkolajenikusewera m'thupi?
Monga taonera, lembani IIkolajenindi gawo lalikulu la minofu ya cartilage.Choncho kuti munthu amvetse bwino ntchito yake, ayenera kuyang’ana ntchito ya chichereŵechereŵe m’thupi.
Cartilage ndi minofu yolimba koma yokhazikika.Pali mitundu yosiyanasiyana ya cartilage m'thupi, iliyonse ili ndi ntchito yake.Chichereŵechereŵe chomwe chimapezeka m'malo olumikizirana mafupa chimakhala ndi ntchito zingapo, monga
- kugwirizana mafupa
- kulola minofu kunyamula kupsinjika kwamakina
- mayamwidwe mantha
- kulola mafupa olumikizidwa kuyenda popanda kukangana
Cartilage imapangidwa ndi ma chondrocytes omwe ndi maselo apadera omwe amapanga zomwe zimadziwika kuti 'extracellular matrix' zomwe zimakhala ndi proteoglycan, elastin fibers ndi type II.kolajeniulusi.
Mtundu IIkolajeniulusi ndiye chinthu chachikulu cha collagenous chomwe chimapezeka mu chichereŵechereŵe.Amagwira ntchito yofunika kwambiri.Amapanga ukonde wa ma fibrils omwe amathandiza kulumikiza ulusi wa proteoglycan ndi elastin kukhala minofu yolimba, koma yosinthika.
