N acetylneuraminic acid thov
N acetylneuraminic acid muaj cov dej ua kom zoo. Nws tuaj yeem ua tau tiav hauv dej, thiab nws cov qauv molecular muaj cov qauv hydrogen uas muaj cov txheej txheej hydrogen, yog li ua tau txheej txheej ntawm cov tawv nqaij molecule zaj duab xis nyob rau saum npoo ntawm daim tawv nqaij. Daim duab no txheej ua tau zoo txo cov evaporation ntawm daim tawv dej noo, yog li tswj hwm cov ntsiab lus ya raws ntawm daim tawv nqaij. Sialic acid kuj muaj kev hygroscopicity zoo. Nws tuaj yeem nqus cov dej noo los ntawm huab cua thiab sib txuas nrog nws los ua cov tshuaj gelatinous. Cov tshuaj no tuaj yeem tsim cov yeeb yaj kiab nruj rau ntawm daim tawv nqaij, tiv thaiv kev ua kom tawv nqaij ntawm cov tawv nqaij noo noo thaum muab cov nyhuv noo noo.
Lub antioxidant muaj peev xwm ntawm sialic acid tseem yog qhov tseem ceeb hauv nws cov kev laus laus. Sialic acid muaj peev xwm tshem tawm dawb radicals thiab inhibit oxidative tawv nqaij los ntawm oxidative kev puas tsuaj thiab qeeb qeeb ntawm cov txheej txheem laus ntawm cov hlwb. Socic acid tuaj yeem txhawb nqa cov xwm txheej ntawm collagen, txhim kho daim tawv nqaij elasticity thiab firmit lub neej sib tsoo, thiab ua kom cov txheej txheem qeeb ntawm cov tawv nqaij laus.
Sialic acid tau zoo inhibit txoj haujlwm ntawm tyrosine hydroxylase, thiab tseem tuaj yeem hloov kho qhov sib npaug ntawm Melanin metabolism hauv daim tawv nqaij. Lub ntsej muag ntxuav hniav dawb thiab cov teeb pom kev zoo rau cov hmoov av somic acid yog bidirectional. Nws tuaj yeem txo cov melanin thiab kho nws cov metabolism, yog li cov tawv nqaij ntxuav hniav dawb thiab pom kev.
Nws ua rau cov tawv nqaij tawv nqaij los ua cov khoom lag luam loj hlob ntxiv, yog li txhawb kev tsim khoom ntawm elastin. Cov ntsiab lus ntawm Elastin nyob rau hauv daim tawv nqaij nce, uas txhawb txoj kev txhawb nqa ntawm daim tawv nqaij thiab txhim kho nws cov kev ruaj khov thiab kev ua haujlwm elastic thiab ua lub luag haujlwm hauv anti wrinkle thiab firming.
Txais tos tiv tauj peb
Rau kaum peb xyoos, zhenyibio tau tsom rau kev tawm tsam kev laus. Raws li cov chaw tsim khoom tshaj lij ntawm n acetylneuraminic acid, peb txuas ntxiv txhim kho cov txheej txheem ntau lawm thiab ntxiv dag zog rau cov kev pab sib koom tes.
