Yintoni iPeptide?

Iipeptides zikhompawundi ukuba ezimbini okanye ngaphezulu ezimbini amino acids ezidityaniswe peptide bond.Ziyinto ephakathi phakathi kwe-amino acids kunye neprotheyini, kunye nesondlo kunye nesiseko sezinto zeeseli kunye nobomi.

Ukususela ekufumaneni iprotheyini kwi-1838, ukuya ekufumaneni kokuqala kwe-polypeptide emzimbeni womntu ngababini be-physiologists u-Bayliss kunye no-Starling kwiYunivesithi yaseLondon School of Medicine ngo-1902. I-Peptides ifunyenwe ngaphezu kwekhulu leminyaka.

Intlanzi yolwandle olunzulu icollagen peptide itsalwa kwiintlanzi zaselwandle ezinongcoliseko lwasimahla.Ukuzinza kwayo kugqwesileyo ngakumbi kune-molecule ye-collagen eqhelekileyo.Ngeempawu zokumelana nobushushu ngakumbi, ukuxhathisa kwe-asidi kunye ne-alkali, kunye nokuchasana ne-denaturation, inokufunxwa ngokuthe ngqo ngumzimba womntu ngaphandle kokugaya kunye nokuqulunqa ngephecana lesisu.Intoni's ngakumbi, ineenzuzo zokunciphisa umthwalo we-metabolic wezintso kwaye ibonelele umzimba womntu ngeprotheyini ekumgangatho ophezulu kwaye efunxa ngokulula ngakumbi.

Intlanzi yaselwandle i-peptide ephantsi inokwenza i-calcium idityaniswe ngokusondeleyo kunye neeseli zethambo, ngaphandle kokulahlekelwa okanye ukuwohloka.

I-peptide yentlanzi yolwandle enzulu inokukhuthaza ukufunxwa kwe-calcium, i-network structure ye-collagen ibaluleke kakhulu ekugcineni ingqibelelo yesakhiwo samathambo kunye neepropati ze-biomechanical.I-polypeptides kwi-collagen inokuthintela ukubunjwa kwamabala ngokuhlala umsebenzi we-tyrosinase.
