M'zaka zaposachedwa, "ma peptides" akhala akudziwika pazamankhwala osiyanasiyana azaumoyo ndi thanzi. Wokondedwa ndi ogula odziwa bwino zinthu, ma peptides asintha kuyambira pakusamalira tsitsi koyambirira ndi zowonjezera mpaka mizere yamasiku ano yosamalira khungu. Tsopano, iwo akuyamikiridwa ngati chinthu chachikulu chotsatira pambuyo pa hyaluronic acid. Koma kodi ma peptides ndi chiyani kwenikweni, ndipo nchifukwa ninji amalandira chidwi chotere?
Kodi Peptides Ndi Chiyani?
Kuti timvetsetse ma peptides, choyamba tiyenera kumvetsetsa liwu loti "peptide" palokha. Peptide ndi gulu lopangidwa ndi ma α-amino acid olumikizidwa pamodzi ndi ma peptide bond. Ndi chinthu chachilengedwe chomwe chimapezeka m'thupi la munthu ndipo nthawi zambiri chimayimira mapuloteni omwe amawonongeka.
Ndiye, kodi ma peptides ndi gulu la amino acid? Kwenikweni, inde. Kuchuluka kwa mayunitsi amino acid kumatsimikizira mtundu wa peptide: ma amino acid awiri amapanga dipeptide, atatu amapanga tripeptide, ndi zina zotero. Unyolo ukapitilira 50 amino acid, umadziwika kuti ndi mapuloteni. Nthawi zambiri, peptide iliyonse yopangidwa ndi ma amino acid atatu kapena kupitilira apo imatchedwa apolypeptide.
M'thupi la munthu, ma peptides amagwira ntchito zofunika kwambiri pazachilengedwe - kuwongolera mahomoni, kuthandizira kulumikizana kwa neural, kuthandizira kubereka, komanso kuthandizira kukula kwa maselo. Amatha kuyambitsa ma enzyme, kuwongolera kulembedwa kwa DNA, ndi kukhudza kaphatikizidwe ka mapuloteni, potero kumayambitsa zovuta zakuthupi. M'malo mwake, zinthu zambiri zomwe zimagwira ntchito m'matupi athu zimakhala mu mawonekedwe a peptide, zomwe zimawapangitsa kukhala ofunikira paumoyo wamunthu.
Peptides mu Skincare: Ntchito ndi Mitundu
Mu skincare, ma peptides nthawi zambiri amagawidwa kutengera ntchito yawo yayikulu, kuphatikizachizindikiro cha peptides, ma peptides onyamula,ndipeptides inhibitor.
Ma sign peptides amakhala ngati amithenga, kutumiza ma cell akhungu kuti alimbikitse kupanga kolajeni ndi elastin. Izi zimapangitsa kuti khungu likhale lolimba, lowoneka lachinyamata komanso limapereka ubwino wotsutsa kukalamba. Zitsanzo zodziwika bwino ndi Palmitoyl Pentapeptide-3, Palmitoyl Tripeptide-1, Palmitoyl Hexapeptide, ndi Palmitoyl Tripeptide-5.
Ma peptides onyamula amathandizira kunyamula zinthu, monga mkuwa, kupita ku malo a enzymatic. Izi zimathandizira kupanga collagen ndi elastin, zimathandizira kuchira kwa bala, komanso zimathandizira kupanga mitsempha yatsopano yamagazi. Chitsanzo chodziwika bwino ndi Copper Tripeptide-1.
Ma inhibitor peptides amagwira ntchito mwa kupumula minofu ya nkhope, kufewetsa makwinya obwera chifukwa cha kusuntha kwa minofu mobwerezabwereza. Ma peptides awa ndiwotchuka kwambiri pazosamalira nkhope zomwe zimayang'ana mizere yowonetsera. Zitsanzo ndi monga Acetyl Hexapeptide-3, Acetyl Octapeptide-1, zochokera ku dipeptide za njoka ya njoka, ndi Pentapeptide-3.
Kodi Pali Zoipa Zilizonse?
Poyerekeza ndi zinthu zomwe zimagwira ntchito mwachangu monga AHAs kapena retinoids, ma peptides amakonda kupereka zotsatira pang'onopang'ono. Zotsatira zowoneka zimatha kutenga milungu kapena miyezi kuti ziwonekere, zomwe zikutanthauza kusasinthasintha komanso kuleza mtima ndizofunikira mukamagwiritsa ntchito khungu lopangidwa ndi peptide.
Kuphatikiza apo, kutulutsa kwa peptide ndi kaphatikizidwe ndizovuta zomwe zimapangitsa kuti pakhale ndalama zambiri zopangira. Zotsatira zake, zinthu zabwino za peptide nthawi zambiri zimakhala zodula. Ogula akuyenera kusamala ndi zinthu zotsika mtengo zomwe zimati zili ndi ma peptides, chifukwa kuchuluka kwake kapena mphamvu zake zingakhale zokayikitsa.
Beyond Skincare: Ntchito Zachipatala
Ma peptides sizinthu zongosamalira khungu - akupezanso chidwi pazachipatala. Akufufuzidwa kuti agwiritsidwe ntchito mu katemera wa peptide, antimicrobial agents, ndi zina zatsopano zamankhwala. Pamene kafukufuku akupitilirabe kusinthika, kuthekera kokulirapo kwa ma peptides paumoyo wamunthu ndi mankhwala akuyembekezeka kukula kwambiri.
