Kodi Peptide ndi chiyani?

Peptide imanena za mtundu wa mitundu yomwe amino acid ndi mapuloteni, imapangidwa ndi mitundu 20 ya amino acid osiyanasiyana komanso makonzedwe a ma dripeplary. Peputeyi iliyonse ili ndi mawonekedwe awo apadera, ndipo kapangidwe kapepala kosiyanasiyana kumadalira ntchito yawo. Peptide amafufuza zinthu zachilengedwe m'thupi, koma limakhala ndi zinthu zapadera zathupi. Pakati pawo, ma peptide omwe amatha kuwongolera zochitika za thupi zomwe zimatchedwa kuti ntchito peptive peptide kapena bilology yogwira pake. Kumayambiriro kwa 20^thZaka zambiri, kupambana kwa kapangidwe kake ka manyowa kumapangitsa mawonekedwe a pambale.

Zowona zambiri zimatsimikizira kuti mapuloteni satha kuyamwa mu mawonekedwe a amino acid, komanso amamwanso m'mitundu yambiri ya nsonga zambiri. Amakhulupirira kuti ma dripptides ndi ma tripeptis amalowetsedwa m'matumba am'matumbo kenako ma hydrolyzed ndi peptidase kuti alowe magazi amtundu wa ma amino am'mino. Chonyamula peputidi chikulowa mkati.

Kafukufukuyu anapeza kuti mapuloteni omwe amaphatikizidwa ndi thupi la munthu amagayidwa ndikulowetsedwa mu mawonekedwe a michere ya michere, ndipo gawo la mayamwa mu mawonekedwe a Amino a Amino ndi ochepa kwambiri.

Mapuloteni amalowetsedwa mu peptide, zomwe sizingopewera mpikisano pakati pa amino acids, komanso amachepetsa kusintha kwa kuchuluka kwa osmotic pa thupi la anthu. Chifukwa chake, perekani zinthu zopatsa thanzi kwa thupi laumunthu mu mawonekedwe a peptide ndibwino kuti mugwire ntchito mofulumira. Zowonjezera, zosinthika zachilengedwe komanso phindu la peptide ndipamwamba kuposa ma amino acid. Chifukwa chake, ku Depgen pakhala malo otentha kwambiri mu kafukufuku wa zopatsa thanzi, komanso pepti ya taleculal yaying'ono kapena oligopteina amapanga chakudya chopatsa thanzi pakamwa ali ndi sayansi.
