Peptide ndi chiyani?

Ma peptides ndi mankhwala omwe ma amino acid awiri kapena kupitilira apo olumikizidwa ndi ma peptide.Ndi zinthu zapakatikati pakati pa ma amino acid ndi mapuloteni, ndi michere ndi zinthu zofunika za maselo ndi moyo.

Kuchokera pakupeza mapuloteni mu 1838, mpaka kutulukira koyamba kwa polypeptide m'thupi la munthu ndi akatswiri awiri a sayansi ya zamoyo Bayliss ndi Starling ku yunivesite ya London School of Medicine ku 1902. Peptides apezeka kwa zaka zoposa zana.

Nsomba za m'nyanja zakuya collagen peptide imachokera ku nsomba za m'nyanja ndi kuipitsa kwaulere.Kukhazikika kwake ndikwabwino kwambiri kuposa molekyulu wamba wa collagen.Ndi mikhalidwe ya kukana kutentha kwambiri, kukana kwa asidi ndi alkali, komanso kukana kutulutsa, imatha kutengeka mwachindunji ndi thupi la munthu popanda kugaya komanso kupanga kudzera m'matumbo am'mimba.Chani'Kuonjezera apo, ili ndi ubwino wochepetsera kagayidwe kake ka impso ndikupatsa thupi la munthu mapuloteni abwino kwambiri komanso osavuta kuyamwa.

Nsomba zam'madzi zotsika peptide zimatha kupanga calcium yolumikizana kwambiri ndi maselo am'mafupa, popanda kutayika kapena kuwonongeka.

Peptide ya m'nyanja yakuya imatha kulimbikitsa kuyamwa kwa kashiamu, kapangidwe ka maukonde a kolajeni ndikofunikira kwambiri kuti pakhale kukhulupirika kwa kapangidwe ka fupa ndi fupa la biomechanical.Ma polypeptides mu collagen amatha kulepheretsa mapangidwe a madontho mwa kukhala ndi ntchito ya tyrosinase.
