collagen, mtundu wa mapuloteni opangidwa mu extracellular matrix, amatchedwa Collagen, yomwe idachokera ku Greek.Collagen ndi mapuloteni oyera, opaque komanso opanda nthambi omwe amapezeka pakhungu, mafupa, cartilage, mano, tendons, ligaments ndi mitsempha ya magazi a nyama.Ndilofunikira kwambiri puloteni yamapangidwe amtundu wolumikizana, ndipo imagwira ntchito yothandizira ziwalo ndikuteteza thupi.Collagen ndi mapuloteni ochuluka kwambiri pa zinyama, zomwe zimakhala 25% mpaka 30% ya mapuloteni onse m'thupi, ofanana ndi 6% ya kulemera kwa thupi.
M'zaka zaposachedwa, ndi chitukuko cha teknoloji yotulutsa collagen ndi maphunziro ozama pa mapangidwe ake ndi katundu wake, ntchito zamoyo za collagen hydrolysates ndi polypeptides zakhala zikudziwika pang'onopang'ono.Kafukufuku ndi kugwiritsa ntchito collagen kwakhala malo opangira kafukufuku wazachipatala, chakudya, zodzoladzola ndi mafakitale ena.
Kuphatikiza pa tryptophan ndi cysteine, kolajeni ili ndi ma amino acid 18, 7 omwe ndi ofunikira kuti munthu akule.Glycine yomwe ili mu kolajeni imakhala 30%, ndipo proline ndi hydroxyproline pamodzi zimakhala pafupifupi 25%, yomwe ndi yapamwamba kwambiri pakati pa mitundu yonse ya mapuloteni.Zomwe zili mu alanine ndi glutamic acid ndizokwera kwambiri.Kuphatikiza apo, ilinso ndi hydroxyproline ndi pyroglutamic acid, zomwe siziwoneka kawirikawiri m'mapuloteni wamba, ndi hydroxyllysine, yomwe imakhala yosowa m'mapuloteni ena.
Collagen ndi mapuloteni opangidwa mu extracellular matrix momwe mamolekyu ake amaphatikizidwa kukhala ma supramolecular.Kulemera kwa molekyulu ndi 300 ku.Chojambula chodziwika bwino cha collagen ndi mawonekedwe a helix atatu, omwe amakhala ndi ma alpha polypeptides mu unyolo wakumanzere wa alpha, iliyonse yomwe imapindidwa mozungulira kuti ipange mawonekedwe amanja a alpha helix.
Kapangidwe kake ka katatu ka helix ka kolajeni kumapangitsa kuti maselo ake azikhala okhazikika, ndipo amakhala ndi chitetezo chochepa komanso kuyanjana kwabwino.Kapangidwe kameneka kamatsimikizira katundu, ndipo katundu amasankha ntchito.Kusiyanasiyana ndi zovuta zamapangidwe a collagen zimatsimikizira malo ake ofunikira m'magawo ambiri, ndipo zinthu za collagen zimakhala ndi chiyembekezo chabwino chogwiritsa ntchito.
Collagen ndi gulu la mapuloteni.Pafupifupi mitundu 30 ya ma collagen yapezeka, yomwe imatha kupanga mitundu yopitilira 16 ya mamolekyu a kolajeni.Malinga ndi kagawidwe kawo komanso magwiridwe antchito mu vivo, collagen pakadali pano imagawidwa kukhala interstitial collagen, basal membrane collagen ndi pericellular collagen.Mamolekyu a interstitial collagen amakhala ndi ma collagen ambiri m'thupi lonse, kuphatikiza mamolekyu a Ⅰ, Ⅱ ndi Ⅲ collagen, omwe amagawidwa kwambiri pakhungu, tendon ndi minofu ina, yomwe mtundu wa Ⅱ collagen umapangidwa ndi chondrocytes.Collagen yapansi panthaka nthawi zambiri imatchedwa mtundu wa Ⅳ collagen, womwe umagawidwa kwambiri mumpanda wapansi.Kolajeni ya pericellular, yomwe nthawi zambiri imapanga Ⅴ collagen, imakhala yochuluka mu minofu yolumikizana.
Kulongedza kwathu ndi mtundu wa collagen wa 25KG woyikidwa mu thumba la PE, ndiye thumba la PE limayikidwa mu ng'oma ya fiber yokhala ndi loko.Ng’oma 27 zimapakidwa papalati imodzi, ndipo chidebe chimodzi cha mapazi 20 chimatha kunyamula ng’oma zokwana 800 zomwe ndi 8000KG ngati zili pallet ndi 10000KGS ngati sizipachikidwa.
Zitsanzo zaulere za pafupifupi magalamu 100 zilipo kuti muyesedwe mukapempha.Chonde titumizireni kuti tipemphe zitsanzo kapena ndemanga.
Tili ndi akatswiri ogulitsa omwe amayankha mwachangu komanso molondola pazofunsa zanu.Tikulonjeza kuti mudzalandira yankho la funso lanu mkati mwa maola 24.
