Yini i-peptotide?

I-Peptide isho uhlobo lwengxenye yesakhiwo sayo phakathi kwe-amino acid kanye namaprotheni, yakhiwa izinhlobo ezingama-20 zama-amino acid ezinombolweni ezahlukahlukene noma ama-polyppepdes ezinhlaka. Yonke i-peptide inesakhiwo sabo esiyingqayizivele, kanye nokwakheka kwama-poptides ahlukene ancike emsebenzini wawo. I-Peptide ilandelela okuqukethwe emzimbeni webhayoloji, kepha inomsebenzi ohlukile ngokomzimba. Phakathi kwazo, ama-ceptides angalawula umzimba womzimba womzimba obizwa ngokuthi yi-peptide esebenzayo noma i-peptide esebenzayo yemvelo. Ekuqaleni kuka-20^thIkhulu, impumelelo yokwakhiwa kwamakhemikhali amakhemikhali abonakala ukubukeka kwesayensi ye-peptide.

Amaqiniso amaningi afakazela ukuthi amaprotheni awakwazi ukukhipha kuphela ngesimo se-amino acid, kepha futhi amunca ngezindlela eziningi ze-peptides. Ngokuvamile kuzwakala ukuthi amaDideptides kanye nama-Triptides angena emasontweni amathumbu abese e-hydrolyzed yi-peptudase ukungenela ukujikeleza kwegazi ngesimo samahhala ama-amino acid. Isithwali se-peptide singena ekusakazweni.

Ucwaningo luphinde lwathola ukuthi amaprotheni athathwa ngumzimba womuntu agaywe futhi amunca ngendlela yama-oligopeptides ngemuva kwesenzo sama-enzyme epheshana lokugaya ukudla, kanye nengxenye yokutholwa ngohlobo lwamahhala lwe-amino acid lincane kakhulu.

Amaprotheni amunwa ngendlela ye-peptide, engagcini nje ngokucophelela umncintiswano phakathi kwama-amino acid, kepha futhi anciphise umphumela wokubuyela emuva kwengcindezi ephezulu yomzimba womuntu. Ngakho-ke, hlinzeka ngento yokudla okunempilo emzimbeni womuntu ngendlela ye-peptide ilungele ukuphakama ngokushesha okusebenzayo kwe-peptide. Ngaphezu kwalokho, ubuqili bemvelo kanye nenani lokudla okunempilo ye-peptide liphakeme kunama-amino acid amahhala. Ngakho-ke, i-portide ye-collagen iba yindawo entsha eshisayo emkhakheni wokucwaninga okunempilo kwamaprotheni, kanye ne-oligopeptide ye-oligopeptide yenza ukudla okunempilo okunempilo kunesisekelo sesayensi.
