Qhov sib txawv tseem ceeb ntawm Azelaic acid thiab niacinamide yog azelaic acid pab ua kom lub siab rhiab thiab txo cov kab mob tom qab, thaum niacinamide pab txo qhov pores thiab muaj cov khoom thaiv-kho kho.
Ob leeg azelaic acid thiab niacinamide feem ntau yog siv rau hauv kev lag luam tshuaj pleev ib ce thiab kev tu tawv nqaij kom cov tawv nqaij du thiab meej nrog cov khoom tu zoo nkauj. Ob qho no yog cov tshuaj antioxidants uas tuaj yeem muab ntau yam ntawm daim tawv nqaij-txhim kho cov txiaj ntsig. Txawm li cas los xij, muaj kev sib cais siv rau txhua qhov sib xyaw uas tsis yog qhov kev siv ntau. Piv txwv li, niacinamide tuaj yeem txo qhov pores hauv daim tawv nqaij, thaum azelaic acid tuaj yeem ua kom lub siab ntawm daim tawv nqaij.
Azelaic Acid yog dab tsi?
Azelaic acid yog cov organic compound uas muaj cov tshuaj formula HOOC(CH2)7COOH. Cov tshuaj no tuaj nyob rau hauv qeb ntawm dicarboxylic acids vim nws muaj ob pawg carboxylic acid ua haujlwm. Azelaic acid zoo nkaus li cov hmoov dawb, thiab cov kua qaub no feem ntau tshwm sim hauv cov nplej, barley, thiab rye nroj tsuag. Ntxiv mus, azelaic acid yog lub hauv paus rau ntau lub tebchaw, suav nrog cov polymers thiab plasticizers. Tsis tas li ntawd, nws yog ib qho khoom xyaw hauv ntau cov plaub hau thiab cov tawv nqaij txias.
Cov molar loj ntawm azelaic acid yog 188.22 g / mol. Nws yog ib qho aliphatic molecule uas muaj carboxylic acid pawg ntawm ob kawg ntawm cov saw hlau ntawm carbon atoms. Hauv cov ntawv thov kev lag luam, qhov sib xyaw no yog tsim los ntawm ozonolysis ntawm oleic acid. Txawm li cas los xij, nws yog ib txwm tsim los ntawm qee hom poov xab uas nyob ntawm daim tawv nqaij. Ntxiv mus, cov kab mob degradation ntawm nonanoic acid kuj muab azelaic acid.
Niacinamide yog dab tsi?
Niacinamide yog ib qho organic compound uas muaj cov tshuaj formula C
6H6N2O. Nws tseem hu ua nicotinamide thiab yog ib daim ntawv ntawm vitamin B3. Cov vitamin no tshwm sim hauv qee yam khoom noj (xws li nqaij, ntses, txiv ntseej, nceb, thiab lwm yam), thiab nws kuj muaj muag raws li kev noj haus ntxiv. Qhov kev noj haus ntxiv no tseem ceeb hauv kev kho thiab tiv thaiv pellagra. Ntxiv mus, cov khoom no muaj peev xwm ua kom tawv nqaij, thiab nws yog siv los kho pob txuv ntawm daim tawv nqaij.
Raws li cov tshuaj, niacinamide muaj cov kev mob tshwm sim tsawg kawg nkaus, uas suav nrog cov teeb meem hauv siab ntawm koob tshuaj ntau. Ntxiv mus, cov koob tshuaj ib txwm muaj kev nyab xeeb thaum cev xeeb tub. Niacinamide tuaj yeem tsim kev lag luam los ntawm hydrolysis ntawm nicotinonitriles. Cov tshuaj tiv thaiv no xav tau ib qho catalyst: enzyme nitrile hydratease. Cov enzyme no tso cai rau kev xaiv synthesis ntawm niacinamide. Ntxiv mus, peb tuaj yeem ua qhov sib xyaw no los ntawm nicotinic acid.
Kev kho mob ntawm niacinamide suav nrog kev kho mob ntawm niacin deficiency, kho pob txuv ntawm daim tawv nqaij, txo qis kev pheej hmoo ntawm qog nqaij hlav tawv nqaij, thiab lwm yam.
Qhov txawv ntawm Azelaic Acid thiab Niacinamide yog dab tsi?
Azelaic acid thiab niacinamide yog qhov tseem ceeb hauv kev tsim cov khoom siv tawv nqaij. Azelaic acid yog cov organic compound uas muaj cov tshuaj formula HOOC(CH2)7COOH thaum niacinamide yog cov organic compound uas muaj cov tshuaj formula C 6H6N2O. Qhov sib txawv tseem ceeb ntawm Azelaic acid thiab niacinamide yog tias azelaic acid pab ua kom lub siab rhiab heev thiab txo cov kab mob tom qab, thaum niacinamide pab txo qhov pores thiab muaj kev tiv thaiv kev kho. Ntxiv mus, azelaic acid feem ntau haum rau cov tawv nqaij oily, whereas niacinamide yog haum rau cov tawv nqaij qhuav.
Cov ntawv qhia hauv qab no nthuav tawm qhov sib txawv ntawm Azelaic acid thiab niacinamide hauv daim ntawv qhia rau kev sib piv ntawm ib sab.
Summary – Azelaic Acid vs Niacinamide
Azelaic acid yog cov organic compound uas muaj cov tshuaj formula HOOC(CH2)7COOH. Niacinamide yog cov organic compound uas muaj cov tshuaj formula C6H6N2O. Qhov sib txawv tseem ceeb ntawm Azelaic acid thiab niacinamide yog tias azelaic acid pab ua kom lub siab rhiab heev thiab txo cov kab mob tom qab, thaum niacinamide pab txo qhov pores thiab muaj kev cuam tshuam-kho cov khoom.
