Ceramides CAS 100403-19-8
Musanganiswa wemaceramides une hydroxy uye isiri-hydroxy fatty acid-ine ceramides. Ceramides inogadzirwa kubva ku sphingomyelin kuburikidza nekushandiswa kwe sphingomyelinases kana kuburikidza ne de novo synthesis nzira, iyo inoda kurongeka kwekuita kwe serine palmitoyl transferase uye ceramide synthase. Ivo vakaratidzirwa kupindirana antiproliferative mhinduro senge apoptosis, kukura kusungwa, kusiyanisa, uye senescence.

1.Moisturizing effect: ceramide ndiyo chikamu chikuru cheganda stratum corneum lipid, inogona kubatsira kugadzirisa ganda rekudzivirira rinogona kuita kuti ganda rive rakanyorova uye rinopenya. Asi ceramide inodzikira nezera, uye ganda pasina iro rinogomara nekuoma.
2.Barrier effect: ceramide yakakwana muganda inogona kudzivisa kukurudzirwa kwekunze, asi pasina kana pasina, ganda richarasikirwa nemaitiro ekudzivirira echisikigo, uye hapana simba rekudzivirira kune zvose zvekunze kwemuviri, biological uye mamwe Chemicalbook kukuvara. Semuenzaniso, ganda rinowanzopiswa nezuva kana riri kuzuva, uye zviri nyore kutsvuka kana kunze kuchitonhora.
3.Anti-allergy effect: Iyi iEvhangeri yeshangu dzevana dzakatetepa ganda, ceramide inogona kubatsira kukora stratum corneum, kuwedzera kushivirira kweganda rose, kudzivirira kubva kunze kwezvinhu zvinokuvadza, kudzivirira kunzwa, uye kugadzirisa basa reropa dzvuku. .
4.Kuwedzera, ceramide ine yakanaka kwazvo inopesana nekuchembera, yekubatsira chena uye antioxidant effect.
