collagen, ib yam ntawm cov qauv protein nyob rau hauv lub extracellular matrix, yog hu ua Collagen, uas hloov los ntawm Greek.Collagen yog dawb, opaque thiab unbranched fibrous protein feem ntau pom nyob rau hauv daim tawv nqaij, pob txha, pob txha mos, hniav, tendons, ligaments thiab cov hlab ntsha ntawm cov tsiaj.Nws yog ib qho tseem ceeb heev cov txheej txheem protein ntawm cov ntaub so ntswg sib txuas, thiab ua lub luag haujlwm hauv kev txhawb nqa lub cev thiab tiv thaiv lub cev.Collagen yog cov protein ntau tshaj plaws hauv cov tsiaj, suav txog 25% txog 30% ntawm tag nrho cov protein hauv lub cev, sib npaug li 6% ntawm lub cev hnyav.
Nyob rau hauv xyoo tas los no, nrog rau kev txhim kho ntawm collagen extraction technology thiab kev tshawb fawb tob ntawm nws cov qauv thiab cov khoom, cov kev ua haujlwm lom neeg ntawm collagen hydrolysates thiab polypeptides tau maj mam lees paub.Kev tshawb fawb thiab kev siv ntawm collagen tau dhau los ua kev tshawb fawb hotspot hauv kev kho mob, zaub mov, tshuaj pleev ib ce thiab lwm yam lag luam.
Ntxiv nrog rau tryptophan thiab cysteine, collagen muaj 18 amino acids, 7 ntawm qhov tseem ceeb rau tib neeg txoj kev loj hlob.Cov glycine hauv collagen suav txog 30%, thiab proline thiab hydroxyproline ua ke suav txog li 25%, uas yog qhov siab tshaj plaws ntawm txhua hom proteins.Cov ntsiab lus ntawm alanine thiab glutamic acid kuj tseem siab.Tsis tas li ntawd, nws kuj muaj hydroxyproline thiab pyroglutamic acid, uas tsis tshua pom muaj nyob rau hauv cov protein ntau, thiab hydroxyllysine, uas yuav luag tsis muaj nyob rau hauv lwm cov proteins.
Collagen yog cov txheej txheem protein nyob rau hauv extracellular matrix nyob rau hauv uas nws cov molecules yog aggregated rau hauv supramolecular lug.Qhov hnyav molecular yog 300 ku.Qhov feem ntau cov qauv ntawm collagen yog ib tug triple helix qauv, uas muaj peb alpha polypeptides nyob rau hauv ib tug laug-tes alpha saw, txhua tus uas yog twisted ib ncig los tsim ib txoj cai-tes alpha helix qauv.
Qhov tshwj xeeb triple helix qauv ntawm collagen ua rau nws cov qauv molecular ruaj khov, thiab nws muaj cov immunogenicity tsawg thiab zoo biocompatibility.Cov qauv txiav txim siab cov cuab yeej, thiab cov cuab yeej txiav txim siab siv.Kev sib txawv thiab kev sib txawv ntawm cov qauv collagen txiav txim siab nws txoj haujlwm tseem ceeb hauv ntau qhov chaw, thiab cov khoom collagen muaj cov ntawv thov zoo.
Collagen yog tsev neeg ntawm cov proteins.Tsawg kawg 30 coding noob ntawm collagen chains tau pom, uas tuaj yeem tsim ntau dua 16 hom collagen molecules.Raws li lawv cov kev faib tawm thiab cov yam ntxwv ua haujlwm hauv vivo, collagen tam sim no muab faib ua interstitial collagen, basal membrane collagen thiab pericellular collagen.Interstitial collagen molecules account rau feem coob ntawm collagen nyob rau hauv tag nrho lub cev, xws li hom Ⅰ, Ⅱ thiab Ⅲ collagen molecules, uas yog feem ntau faib rau hauv daim tawv nqaij, leeg thiab lwm yam ntaub so ntswg, ntawm cov hom Ⅱ collagen yog tsim los ntawm chondrocytes.Hauv qab daus daim nyias nyias collagen feem ntau yog hu ua hom Ⅳ collagen, uas yog feem ntau faib rau hauv qab daus daim nyias nyias.Pericellular collagen, feem ntau yog hom Ⅴ collagen, muaj nyob hauv cov ntaub so ntswg sib txuas.
Peb Ntim yog 25KG collagen hom muab tso rau hauv ib lub hnab PE, ces lub hnab PE muab tso rau hauv ib lub nruas fiber ntau nrog lub xauv.27 lub nruas yog palleted rau hauv ib lub pallet, thiab ib lub thawv 20 ko taw muaj peev xwm thauj tau ib ncig ntawm 800 nruas uas yog 8000KG yog palleted thiab 10000KGS yog tsis palleted.
Cov qauv dawb ntawm ib ncig ntawm 100 grams yog muaj rau koj qhov kev sim raws li qhov kev thov.Thov hu rau peb kom tau txais cov qauv lossis cov lus hais.
Peb muaj cov kws tshaj lij kev muag khoom uas muab cov lus teb sai thiab raug rau koj cov lus nug.Peb cog lus tias koj yuav tau txais cov lus teb rau koj qhov kev nug hauv 24 teev.
