Kwiminyaka yakutshanje, "iipeptides" ziye zaba buzzword kuluhlu olubanzi lweemveliso zempilo kunye nempilo. Ithandwa ngabathengi bezithako-savvy, iipeptides zenze indlela yazo ukusuka kukhathalelo lweenwele kwangoko kunye nezongezelelo ukuya kwimigca yokhathalelo oluphezulu lwanamhlanje. Ngoku, banconywa njengento enkulu elandelayo emva kwe-hyaluronic acid. Kodwa yintoni kanye kanye i-peptides, kwaye kutheni ifumana ingqalelo engaka?
Yintoni iiPeptides?
Ukuze siqonde iipeptides, kufuneka siqale siqonde igama elithi “peptide” ngokwalo. I-peptide yikhompawundi eyenziwe nge-α-amino acids edityaniswe kunye ngamabhondi e-peptide. Yinto yendalo eqhelekileyo efumaneka emzimbeni womntu kwaye ihlala imele imveliso ephakathi yeeproteni.
Ke, ngaba iipeptides yingqokelela yeeamino acids? Enyanisweni, ewe. Inani leeyunithi ze-amino acid limisela uhlobo lwe-peptide: i-amino acids ezimbini zenza idipeptide, ezintathu zenza i-tripeptide, njalo njalo. Emva kokuba ikhonkco lingaphezulu kwama-amino acids angama-50, ngokuqhelekileyo lihlelwa njengeprotheni. Ngokubanzi, nayiphi na i-peptide eyenziwe ngee-amino acids ezintathu okanye ngaphezulu kubhekiselwa kuyo njengei-polypeptide.
Emzimbeni womntu, iipeptides zidlala indima ebalulekileyo kwimisebenzi eyahlukeneyo yebhayoloji-ukulawula iihomoni, ukuxhasa unxibelelwano lwe-neural, ukunceda ekuveliseni, kunye negalelo ekukhuleni kweeseli. Banokusebenzisa i-enzymes, balawule ukubhalwa kwe-DNA, kwaye baphembelele iprotheni synthesis, ngaloo ndlela kubangele iziphumo ezithile zomzimba. Ngapha koko, izinto ezininzi ezisebenzayo emizimbeni yethu zikhona kwifomu ye-peptide, ezenza zibaluleke kakhulu kwimpilo yabantu.
Iipeptides kwi-Skincare: Imisebenzi kunye neentlobo
Kwi-skincare, iipeptide zihlala zihlelwa ngokusekwe kumsebenzi wazo ophambili, kubandakanyauphawu peptides, iipeptides ezithwala, kwayeinhibitor peptides.
Iimpawu ze-peptides zisebenza njengezithunywa, zithumela imiqondiso kwiiseli zesikhumba ukuze zikhuthaze ukuveliswa kwe-collagen kunye ne-elastin. Oku kukhokelela ekuqineni, ulusu olubukeka lulutsha kwaye lubonelela ngeenzuzo zokuchasa ukuguga. Imizekelo eqhelekileyo ibandakanya iPalmitoyl Pentapeptide-3, iPalmitoyl Tripeptide-1, iPalmitoyl Hexapeptide, kunye nePalitoyl Tripeptide-5.
Iipeptide ezithwalayo zinceda ukuthutha izinto ezinje ngobhedu, ukuya kwindawo yokusebenza kwe-enzymatic. Oku kukhuthaza ukuveliswa kwe-collagen kunye ne-elastin, inceda ekuphulukiseni amanxeba, kwaye ixhasa ukubunjwa kwemithambo yegazi emitsha. Umzekelo owaziwayo yiCopper Tripeptide-1.
I-inhibitor peptides isebenza ngokukhulula izihlunu zobuso, ukuthambisa imibimbi ebangelwa kukunyakaza okuphindaphindiweyo kwemisipha. Ezi peptides zithandwa kakhulu kwiimveliso zokhathalelo lobuso ezijolise kwimigca yokubonakalisa. Imizekelo iquka i-Acetyl Hexapeptide-3, i-Acetyl Octapeptide-1, i-dipeptide ephuma kwi-snake venom, kunye ne-Pentapeptide-3.
Ngaba kukho Naziphi na iindawo eziDowns?
Xa kuthelekiswa nezithako ezisebenza ngokukhawuleza njenge-AHAs okanye i-retinoids, iipeptides zikholisa ukuhambisa iziphumo ngokuthe ngcembe. Iziphumo ezibonakalayo zinokuthatha iiveki okanye iinyanga ukuba zivele, okuthetha ukuba ukungaguquguquki kunye nomonde ngundoqo xa usebenzisa i-skincare esekwe kwi-peptide.
Ukongeza, ukutsalwa kwe-peptide kunye nokuhlanganiswa ziinkqubo ezinzima ezikhokelela kwiindleko eziphezulu zokuvelisa. Ngenxa yoko, iimveliso ezisemgangathweni zepeptide zihlala zibiza kakhulu. Abathengi kufuneka balumke ngeemveliso ezingabizi kakhulu abathi ziqulethe iipeptides, njengoko ugxininiso lokwenyani okanye ukusebenza ngempumelelo kunokuthandabuzeka.
Ngaphaya kweSkincare: Izicelo zonyango
Iipeptides ayisiyonto nje yokhathalelo lwesikhumba-bakwafumana ukuthambeka kwicandelo lezonyango. Ziyaphononongwa ukuze zisetyenziswe kwizitofu ezisekelwe kwi-peptide, ii-antimicrobial agents, kunye nolunye ulutsha lwamayeza. Njengoko uphando luqhubeka nokuvela, amandla abanzi eepeptides kwimpilo yabantu kunye namayeza kulindeleke ukuba akhule kakhulu.
