Qhov sib txawv tseem ceeb ntawm nicotinic acid thiab nicotinamide yog tias nicotinic acid muaj txiaj ntsig zoo hauv kev kho cov roj cholesterol siab, thaum nicotinamide muaj txiaj ntsig zoo hauv kev kho mob caj dab thiab pellagra.
Nicotinic acid thiab nicotinamide zoo sib xws hauv cov qauv tshuaj. Nicotinamide muaj ib pab pawg amide uas tsis tshua muaj nyob hauv nicotinic acid. Txawm li cas los xij, lawv muaj ntau daim ntawv thov.
Nicotinic Acid yog dab tsi?
Nicotinic acid yog cov organic compound uas muaj cov tshuaj formula C6H5NO2 Nws zoo nkaus li dawb thiab translucent crystals. Nicotinic acid tseem hu ua niacin. Cov tshuaj no yog ib daim ntawv ntawm vitamin B3 thiab tseem yog ib qho tseem ceeb ntawm tib neeg cov zaub mov. Peb feem ntau tau txais nicotinic acid los ntawm cov khoom noj, suav nrog tag nrho cov khoom noj thiab ua tiav. Cov khoom noj uas muab rau peb no suav nrog cov khoom noj uas muaj zog, nqaij, nqaij qaib, ntses liab (xws li, tuna, salmon), txiv ntseej, legumes, thiab noob.
Raws li kev noj haus ntxiv, nicotinic acid yog qhov tseem ceeb hauv kev kho pellagra, uas yog ib qho kab mob uas tshwm sim los ntawm qhov tsis txaus ntawm niacin. Cov tsos mob ntawm qhov tsis muaj qhov sib xyaw no suav nrog cov kab mob ntawm daim tawv nqaij thiab qhov ncauj, anemia, mob taub hau, nkees, thiab lwm yam.
Nicotinamide yog amide derivative ntawm nicotinic acid. Yog li ntawd, peb tuaj yeem siv nicotinamide los kho qhov tsis muaj nicotinic acid. Qhov no yog vim hais tias nicotinamide tuaj yeem siv rau hauv cov nyiaj kho mob los ntawm kev tsis ua kom muaj dej ntws tawm.
Nicotinic acid yog cov dej-soluble khoom uas yog ib tug derivative ntawm pyridine. Nws muaj ib pawg carboxyl ntawm txoj haujlwm carbon-3. Hauv amide derivative nicotinamide, pawg carboxyl no hloov los ntawm pawg carboxamide.
Nicotinamide yog dab tsi?
Nicotinamide tuaj yeem piav qhia raws li cov tshuaj amide muaj cov pab pawg ua haujlwm -C(=O)NH2 Nws yog ib daim ntawv ntawm vitamin B3 thiab muaj nyob rau hauv ntau yam khoom noj.. Piv txwv li, peb tuaj yeem pom cov khoom no hauv cov poov xab, nqaij, mis nyuj, thiab zaub ntsuab. Nicotinamide yog siv los ua tshuaj; peb tuaj yeem siv cov tshuaj no ntawm qhov ncauj los tiv thaiv thiab kho pellagra. Nicotinic acid lossis niacin kuj tseem siv tau los hloov cov txheej txheem no, tab sis tsis zoo li nicotinic acid, nicotinamide tsis ua rau tawv nqaij. Hauv nws daim ntawv cream, peb tuaj yeem siv cov tshuaj no los kho pob txuv. Txawm li cas los xij, nicotinamide yog ib qho amide ntawm nicotinic acid.
Raws li tshuaj, nicotinamide muaj kev phiv tsawg heev. Txawm li cas los xij, thaum muaj cov tshuaj no ntau hauv lub cev, nws tuaj yeem ua rau mob siab. Raws li kev tshawb fawb kev tshawb fawb, koob tshuaj ib txwm muaj kev nyab xeeb rau kev siv thaum cev xeeb tub.
Nyob rau hauv cov qauv tshuaj nicotinamide, muaj ib lub nplhaib pyridine uas ib pawg thawj amide txuas rau hauv txoj hauj lwm meta. Peb tuaj yeem categorize nicotinamide ua ib qho amide ntawm nicotinic acid. Nws yog ib qho aromatic compound. Ntxiv mus, qhov sib xyaw no tuaj yeem raug hloov pauv cov tshuaj electrophilic thiab hloov pauv ntawm nws ob pawg ua haujlwm.
Qhov txawv ntawm Nicotinic Acid thiab Nicotinamide yog dab tsi?
Nicotinic acid thiab nicotinamide zoo sib xws hauv cov qauv tshuaj. Ntawm no, nicotinamide muaj ib pab pawg amide uas tsis tshua muaj nyob hauv nicotinic acid. Qhov sib txawv tseem ceeb ntawm nicotinic acid thiab nicotinamide yog tias nicotinic acid muaj txiaj ntsig zoo hauv kev kho cov roj cholesterol siab, thaum nicotinamide muaj txiaj ntsig zoo hauv kev kho mob caj dab thiab pellagra.
Cov hauv qab no qhia txog qhov sib txawv ntawm nicotinic acid thiab nicotinamide hauv daim ntawv tabular rau kev sib piv ntawm ib sab.
Summary – Nicotinic Acid vs Nicotinamide
Nicotinic acid yog cov organic compound uas muaj cov tshuaj formula C6H5NO2, thaum nicotinamide yog ib qho tshuaj amide uas muaj cov pab pawg ua haujlwm -C(=O)NH2 Qhov sib txawv tseem ceeb ntawm nicotinic acid thiab nicotinamide yog tias nicotinic acid muaj txiaj ntsig zoo hauv kev kho cov roj cholesterol siab, whereas nicotinamide muaj txiaj ntsig zoo hauv kev kho mob caj dab thiab pellagra.
