ma protease (mtundu wolembedwa) wopanga zopanga zatsopano (mtundu wolembedwa)
Mafotokozedwe Akatundu
Protease ndi gawo limodzi la kalasi la ma enzymes omwe hydrolyze mapuloteni pangozi. Amatha kugawidwa mu endopfastidase ndi telopfate molingana ndi njira yomwe amapewetsa ma peptides. Chomwe chakale chimatha kudula kulemera kwakukulu kwa polypeptide unyolo kuchokera pakati kuti apange mikangano yaying'ono ndi peppone; Omalizayo akhoza kugawidwa kukhala Carboxypeptidale ndi Aminopptidase, omwe hydrolyze unyolo wa peptide kapena amino kumapeto kwa polypeptide, motsatana, kwa amino acid.

Kugwira nchito
Mapulote ozungulira nthawi zambiri viscera ya nyama, mbewu zimayambira, masamba, zipatso ndi tizilombo. Mapulotesiri achitetezo amapangidwa ndi nkhungu ndi mabakiteriya, kutsatiridwa ndi yisiti ndi macesiti.
Ma enzyme omwe amathandizira hydrolys a mapuloteni. Pali mitundu yambiri, ofunikira ndi pepsin, trypsin, cathepsin, papain ndi mapuloteni a Boxustis. Mapulotete ali ndi kusamvetseka kwakanthawi kofikira, ndipo mapuloteke amatha kuchita boti inayake mu protein molekyulu, monga periptiyo yopangidwa ndi hydrolysis a acid anticzod ndi trypsin. Mapulotete amagawidwa kwambiri, makamaka mu thirakiti la chiwiya cha anthu ndi nyama, komanso zomera ndi tizilombo tating'onoting'ono. Chifukwa cha nyama zochepa ndi zomera zomera, kupanga kwa zokonzekera zamakampani kumakapangidwe kake kake kake ngati bacillus bacroorlis ndi asrrilgillus.
Karata yanchito
Mapulotete ndi imodzi mwazokonzekera mphamvu yamafakitale yambiri, yomwe imatha kugwirizira hydrolysis ya mapuloteni ndi polypeptide, ndipo imapezeka kwambiri m'magulu a nyama, mbewu, zipatso ndi tizilombo. Mapuloteke amagwiritsidwa ntchito kwambiri mu tchizi, mafuta a nyama komanso kusinthidwa kwa protein. Kuphatikiza apo, pepsin, chymotyryptin, carboxypeptidale ndi aminoptidase ndi mapulotenidwe am'mimba mwamwambo wamunthu, ndipo pansi pa zomwe adachita, mapuloteni omwe amapezeka m'matumbo ang'onoang'ono.
Pakadali pano, mapulotekeji omwe amagwiritsidwa ntchito pophika ophika ndi mapurotesitanti a fungus, matebulo a bacteria ndi mapuloteni azomera. Kugwiritsa ntchito mapulotete mu kupanga mkate kumatha kusintha katundu wa gluten, ndipo mawonekedwe ake ndiwosiyana ndi machitidwe a mphamvu yokonzekera mkate komanso mankhwala omwe amachepetsa. M'malo mophwanya ndalama zolipirira, mapulote amaphwanya ma netiweki atatu omwe amapanga gluten. Udindo wamadzimaliro mu kupanga mkate umawonekera makamaka munthawi ya mtanda. Chifukwa cha protease, mapuloteni mu ufa amawonongeka mu peptides ndi amino acid, kuti apereke gwero la kaboni wa yisiti ndikulimbikitsa nayo kutaya.
