Qhov sib txawv tseem ceeb ntawm alpha arbutin thiab vitamin C yog tias thaum siv cov khoom tu tawv nqaij, alpha arbutin muaj zog ntau dua rau cov tawv nqaij-brightening dua vitamin C hauv cov khoom tu tawv nqaij.
Alpha arbutin thiab vitamin C yog cov organic tebchaw uas muaj txiaj ntsig zoo hauv kev tsim cov khoom siv tawv nqaij. Ob lub tebchaw no ua cov khoom xyaw ua lub luag haujlwm rau daim tawv nqaij-brightening thiab tawv nqaij lightening.
Alpha Arbutin yog dab tsi?
Alpha arbutin yog ib qho organic compound uas tuaj yeem txheeb xyuas tau tias yog ib qho derivative ntawm hydroquinone. Nws muaj cov tshuaj formula C12H16O7Cov molar loj ntawm cov tshuaj no yog 272.25 g / mol. Nws zoo nkaus li cov hmoov dawb crystalline, thiab qhov ceev ntawm qhov sib xyaw no tuaj yeem muab tau raws li 1.55 g / cm 3 Lub melting point ntawm alpha arbutin ranges ntawm 195-196 degrees Celsius, thaum lub boiling. taw tes nyob ntawm 561.6 degrees Celsius.
Cov tshuaj no tuaj yeem thaiv cov biosynthesis ntawm melanin ntawm daim tawv nqaij los ntawm inhibition ntawm enzymatic oxidation ntawm Tyrosine thiab Dopa, thiab nws kuj txhawb cov tawv nqaij lightening. Ntxiv mus, qhov sib xyaw no tuaj yeem txwv melanogenesis los ntawm kev thaiv cov txheej txheem ntawm tyrosinase, txo qis cov xim daj daj xim av, thiab lwm yam.
Alpha arbutin yog qhov tseem ceeb ua cov khoom siv hauv cov khoom tu tawv nqaij vim tias nws tuaj yeem tawm thiab ci tawv nqaij, ua kom pom kev tsaus ntuj, txo qhov pom ntawm caws pliav, thiab lwm yam. Alpha arbutin muab cov nyhuv no thaum nws cuam tshuam nrog melanin hauv daim tawv nqaij. Cov tawv nqaij qee zaum ua rau melanin ntau dhau thiab tuaj yeem ua rau hyperpigmentation. Kev raug rau lub hnub, cev xeeb tub, thiab siv qee yam tshuaj tuaj yeem ua rau hyperpigmentation. Arbutin tuaj yeem ua rau txoj hauv kev melanin txhawm rau txo qis melanin kev ua haujlwm.
Txoj kev melanin tuaj yeem piav qhia raws li cov txheej txheem nyuaj uas cov tawv nqaij tsim pigmentation. Ntau yam sib txawv ntawm daim tawv nqaij-brightening cov khoom xyaw tuaj yeem ua thaum lub sijhawm sib txawv ntawm cov txheej txheem no txhawm rau txhawm rau ua haujlwm ntawm tyrosinase, lub enzyme uas yog lub luag haujlwm rau kev tsim melanin.
Vitamin C yog dab tsi?
Vitamin C yog ib qho organic compound uas muaj cov tshuaj formula C6H8O6 Cov molar loj ntawm cov tshuaj no yog 176.12 g / mol. Nws melting point thiab boiling point yog 190 ° C thiab 553 ° C, feem. Cov vitamin no tshwm sim hauv qee hom zaub mov, thiab peb tuaj yeem siv nws ua cov khoom noj ntxiv thiab. Cov ntsiab lus "Ascorbic acid" thiab "L-Ascorbic acid" yog cov lus sib piv rau cov tshuaj no txawm tias lawv txawv me ntsis ntawm ib leeg. Tsis tas li ntawd, nws yog ib qho tseem ceeb rau peb vim tias nws tuaj yeem kho cov ntaub so ntswg hauv lub cev thiab tuaj yeem ua rau kev tsim cov enzymatic ntawm qee cov neurotransmitters. Qhov tseem ceeb tshaj, nws yog ib qho antioxidant.
Lub ntuj qhov chaw ntawm cov vitamin no yog cov txiv hmab txiv ntoo xws li citrus txiv hmab txiv ntoo, kiwifruit, strawberries, thiab lwm yam zaub mov xws li broccoli, nyoos tswb kua txob, thiab lwm yam. Txawm li cas los, ntev cia los yog ua noj ua haus yuav rhuav tshem vitamin C nyob rau hauv cov zaub mov. Qhov tsis txaus ntawm cov vitamin no tuaj yeem ua rau tus kab mob Scurvy. Tus kab mob no tshwm sim thaum lub collagen tsim los ntawm lub cev tsis tuaj yeem ua haujlwm zoo yam tsis muaj vitamin C.
Cov vitamin no muaj nyob rau hauv ob qho tib si ntuj thiab hluavtaws. Peb hu rau daim ntawv purest ntawm vitamin C li "ascorbic acid." Feem ntau, cov ntaub ntawv purest yog ua nyob rau hauv lub chaw soj nstuam. Cov ntaub ntawv ntuj yog ua ke nrog lwm cov khoom. Yog li ntawd, peb yuav tsum ua kom zoo dua thiab ua cov zaub mov kom tau txais cov vitamin tawm ntawm cov khoom noj.
Qhov txawv ntawm Alpha Arbutin thiab Vitamin C yog dab tsi?
Alpha arbutin thiab vitamin C yog ob qho khoom xyaw uas tuaj yeem siv rau hauv cov khoom siv tawv nqaij. Qhov sib txawv tseem ceeb ntawm alpha arbutin thiab vitamin C yog tias thaum siv cov khoom tu tawv nqaij, alpha arbutin muaj zog ntau dua rau cov tawv nqaij ci dua li cov vitamin C hauv cov khoom siv tawv nqaij. Nws raug nquahu kom siv 2% alpha arbutin kom tau txais cov tawv nqaij ci, thaum rau vitamin C, qhov pom zoo concentration yog 10-20%.
Cov hauv qab no qhia txog qhov sib txawv ntawm alpha arbutin thiab vitamin C hauv daim ntawv qhia rau kev sib piv ntawm ib sab.
Summary – Alpha Arbutin vs Vitamin C
Alpha arbutin thiab vitamin C ua lub luag haujlwm tseem ceeb hauv lub cev, tshwj xeeb ntawm daim tawv nqaij. Qhov sib txawv tseem ceeb ntawm alpha arbutin thiab vitamin C yog tias thaum siv hauv cov khoom tu tawv nqaij, alpha arbutin muaj zog ntau dua rau ntawm daim tawv nqaij-brightening dua vitamin C hauv cov khoom tu tawv nqaij.
