Palmitoyl tripeptide-1, izwi kandi nka pal-GHK, ni peptide ya sintetike hamwe na formula ya chimique C16H32N6O5.Nuburyo bwahinduwe bwa peptide karemano GHK, iboneka mubisanzwe muruhu rwacu.Iyi peptide yahinduwe yakozwe kugirango yongere umusaruro wa kolagen hamwe nizindi poroteyine zingenzi kugirango biteze imbere ubuzima rusange nigaragara ryuruhu.
Ibisobanuro nyamukuru byiki gicuruzwa nuko bitera umusaruro wa kolagen.Kolagen ni poroteyine ikomeye ishinzwe kubungabunga imiterere no gukomera kwuruhu.Ariko, uko tugenda dusaza, umubiri wa kamere ya kolagen isanzwe igabanuka, bigatuma habaho iminkanyari, uruhu runyeganyega, nibindi bimenyetso byo gusaza.Palmitoyl Tripeptide-1 ikemura neza ibi byerekana fibroblast mu ruhu kugirango itange kolagen nyinshi.Ibi na byo bifasha kugarura uruhu rworoshye no gukomera, kugabanya ibimenyetso bigaragara byo gusaza no guteza imbere isura yubusore.
