He aha ka collagen type II?
ʻAno IIkolagenahe pūmua fibrillar i hana ʻia me 3 mau kaulahao lōʻihi o nā waikawa amino e hana i kahi pūnaewele paʻa paʻa o nā fibrils a me nā fibers.ʻO ia ka mea nui o ka cartilage i loko o ke kino.Aia i loko o ke kaumaha maloʻo a mekolagen.
ʻAno IIkolagenaʻO ia ka mea e hāʻawi ai i ka cartilage i kona ikaika tensile a me ka elasticity, e hiki ai iā ia ke kākoʻo i nā hono.Kōkua ia i ke kaʻina hana paʻa me ke kōkua o fibronectin a me nā mea ʻē aʻekolagen.
He aha ka ʻokoʻa ma waena o ke ʻano II a me ke ʻano I collagen?
Ma ka ʻili he ʻano like lākou, ʻo kēlā me kēia mea he triple helix ie i hana ʻia me ʻekolu kaulahao loloa o nā waikawa amino.Eia nō naʻe, ma kahi pae molekala he ʻokoʻa koʻikoʻi.
Type I collagen: Ua like ka lua o na kaulahao ekolu.
ʻAno II collagen: Ua like na kaulahao ekolu.
ʻAno ICollagenloaʻa nui ma nā iwi a me ka ʻili.Oiai ke ano IIkolagenaaia wale no ma ka cartilage.
He aha nā pōmaikaʻi o ke ʻano IIkolagenapāʻani i ke kino?
E like me kā mākou i ʻike ai, ʻano IIkolagenahe hapa nui o ka ʻiʻo cartilage.No laila, no ka hoʻomaopopo pono ʻana i kāna hana, pono e nānā i ka hana o ka cartilage i loko o ke kino.
ʻO Cartilage kahi ʻiʻo pili paʻa akā paʻa.Aia nā ʻano like ʻole o ka cartilage i ke kino, kēlā me kēia me kahi hana kikoʻī.ʻO ka cartilage i loaʻa i loko o nā hono he nui nā hana, e like me
- hoʻohui iwi
- ka ʻae ʻana i ka ʻiʻo e amo i ke koʻikoʻi mechanical
- hoʻopaʻa haʻalulu
- ka ʻae ʻana i nā iwi i hoʻopili ʻia e neʻe me ka ʻole o ka hakakā
Hoʻokumu ʻia ka cartilage me nā chondrocytes he mau cell kūikawā e hana i ka mea i ʻike ʻia he 'extracellular matrix' me ka proteoglycan, elastin fibers a me ke ʻano II.kolagenanā pulupulu.
ʻO ke ʻano IIkolagenaʻO ka fiber ka mea nui collagenous i loaʻa i ka cartilage.He kuleana koʻikoʻi ko lākou.Hoʻokumu lākou i kahi pūnaewele o nā fibrils e kōkua i ka hoʻopaʻa ʻana i ka proteoglycan a me ka elastin fibers i loko o kahi ʻiʻo paʻakikī, akā hiki ke maʻalahi.
