Ceramides CAS 100403-19-8
Cov ceramides sib tov muaj hydroxy thiab non-hydroxy fatty acid uas muaj ceramides. Ceramides yog tsim los ntawm sphingomyelin los ntawm kev ua kom sphingomyelinases los yog los ntawm txoj kev de novo synthesis, uas yuav tsum tau muaj kev sib koom tes ntawm serine palmitoyl transferase thiab ceramide synthase. Lawv tau pom tias muaj kev sib haum xeeb los tiv thaiv cov lus teb xws li apoptosis, kev loj hlob raug ntes, sib txawv, thiab kev laus.

1.Moisturizing effect: ceramide yog cov khoom tseem ceeb ntawm daim tawv nqaij stratum corneum lipid, tuaj yeem pab kho cov tawv nqaij barrier tuaj yeem ua rau daim tawv nqaij mos thiab ci. Tab sis ceramide txo qis nrog lub hnub nyoog, thiab daim tawv nqaij tsis muaj nws ua npub thiab qhuav.
2.Barrier nyhuv: txaus ceramide nyob rau hauv daim tawv nqaij muaj peev xwm tiv tau sab nraud stimulation, tab sis tsis muaj los yog tsis, daim tawv nqaij yuav poob nws tej yam ntuj tso tiv thaiv nyhuv, thiab tsis muaj kev tiv thaiv muaj peev xwm rau tag nrho cov sab nraud lub cev, lom thiab lwm yam Chemicalbook puas. Piv txwv li, daim tawv nqaij yog qhov yooj yim rau kev tshav ntuj thaum raug tshav ntuj, thiab nws yooj yim tig liab thaum huab cua txias.
3.Anti-allergy effect: Qhov no yog Txoj Moo Zoo rau cov tawv nqaij nyias ntawm cov menyuam yaus khau, ceramide tuaj yeem pab ua kom tuab ntawm stratum corneum, txhim khu kev ua siab ntev ntawm tag nrho cov tawv nqaij, tiv thaiv cov khoom tsis zoo, tsis txhob hnov qab, thiab kho lub luag haujlwm ntawm cov ntshav liab. .
4. Tsis tas li ntawd, ceramide muaj kev tiv thaiv kev laus zoo heev, pab dawb thiab cov nyhuv antioxidant.
