Collagen ikhoza kugawidwa mu: molekyulu yayikulu collagen ndi ma molekyulu ang'onoang'ono a collagen peptides.
Mkamwa muzakudya zomwe timadya nthawi zambiri zimakhala ndi mamolekyu akuluakulu a mapuloteni okhala ndi molekyulu yolemera ma 300,000 daltons kapena kupitilira apo, omwe samamwedwa mwachindunji akatha kudya, koma amagawika kukhala ma amino acid m'chigayo, ndikudikirira kukonzedwanso. sizikudziwika ngati pamapeto pake amapanga collagen, yomwe imakhala yochepa kwambiri.
Anthu adawongolera collagen ndi kulemera kwa maselo mpaka 6000 daltons pogwiritsa ntchito njira za acid-base ndi enzymatic cleavage ndikuzitcha collagen peptide. Peptide ndi chinthu chomwe chili pakati pa amino acid ndi ma macromolecular protein. Ma amino acid awiri kapena kupitilira apo amakhala opanda madzi ndipo amafupikitsidwa kuti apange zomangira zingapo za peptide kuti apange peptide, ndipo ma peptide angapo amapindika pamiyeso ingapo kuti apange molekyulu ya protein. Ma peptides ndi zidutswa za mapuloteni enieni okhala ndi mamolekyu amtundu wa nanometer, omwe amatengeka mosavuta ndi m'mimba, matumbo, mitsempha yamagazi ndi khungu, ndipo mayamwidwe awo ndi apamwamba kwambiri kuposa mapuloteni akuluakulu a molekyulu.
Ma Collagen peptides okhala ndi molekyulu yolemera ma daltons 6000 kapena kuchepera amagawidwa kukhala ma peptides okhala ndi molekyulu yolemera ma daltons 1000-6000 ndi ma peptides okhala ndi molekyulu yolemera ma daltons 1000 kapena kuchepera. Nthawi zambiri, kuchuluka kwa ma amino acid mu oligopeptide kumachokera pawiri mpaka 9. Malinga ndi kuchuluka kwa ma amino acid mu peptide, pali mayina osiyanasiyana: pawiri wopangidwa ndi kuchepa madzi m'thupi kwa mamolekyu awiri amino acid amatchedwa dipeptide, ndi fanizo lomwelo, pali tripeptide, tetrapeptide, pentapeptide, etc., mpaka naini. peptides; kawirikawiri pawiri kupangidwa ndi madzi m'thupi condensation wa 10-50 amino asidi mamolekyu amatchedwa polypeptide.
M'zaka za m'ma 1960, zatsimikiziridwa kuti oligopeptide ikhoza kutengeka popanda m'mimba, yomwe ingachepetse kwambiri kulemedwa kwa m'mimba ndi chiwindi ndikuwongolera bioavailability; ndipo imatha kutenga nawo gawo mwachindunji mu kaphatikizidwe ka kolajeni yamunthu popanda kusweka kukhala ma amino acid, pomwe peptide siyingakwaniritse izi.
Choncho, muyenera kumvetsera kulemera kwa maselo a collagen peptides mukamagula.
