Qhov sib txawv tseem ceeb ntawm niacin thiab nicotinamide yog tias niacin feem ntau yog siv los kho cov roj cholesterol siab thaum nicotinamide yog siv los kho mob caj dab thiab pellagra.
Niacin thiab nicotinamide yog ob hom thiab cov txiaj ntsig ntawm vitamin B3. Nicotinamide yog amide derivative ntawm niacin.
Niacin yog dab tsi?
Niacin yog ib qho organic compound uas muaj cov tshuaj formula C
6H5NO2 Cov khoom tshwm li dawb thiab translucent crystals. Nws tseem hu ua nicotinic acid. Niacin yog ib daim ntawv ntawm vitamin B3 thiab nws kuj yog ib qho tseem ceeb ntawm tib neeg cov zaub mov. Peb feem ntau tau txais cov khoom sib xyaw no los ntawm cov khoom noj, suav nrog cov khoom noj tag nrho thiab ua tiav. Cov khoom noj uas muab niacin rau peb suav nrog cov khoom noj uas muaj zog, nqaij, nqaij qaib, ntses liab (xws li tuna, salmon), txiv ntseej, legumes thiab noob.
Daim duab 01: Cov Qauv Tshuaj ntawm Niacin
Raws li kev noj haus ntxiv, niacin muaj txiaj ntsig zoo hauv kev kho mob pellagra, uas yog tus kab mob los ntawm qhov tsis txaus ntawm niacin. Cov tsos mob ntawm niacin deficiency muaj xws li qhov txhab ntawm daim tawv nqaij thiab qhov ncauj, anemia, mob taub hau, nkees, thiab lwm yam.
Nicotinamide yog amide derivative ntawm niacin. Yog li ntawd, peb tuaj yeem siv nicotinamide ua kev kho mob rau niacin deficiency. 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.
Niacin tuaj yeem piav qhia tias yog cov dej-soluble khoom uas yog ib qho 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 yog cov organic compound uas muaj kev ua haujlwm -C(=O)NH2 Nws yog amide. Nicotinamide yog ib daim ntawv ntawm vitamin B3, thiab peb tuaj yeem pom cov khoom sib xyaw no hauv cov khoom noj. E.g. peb tuaj yeem pom cov khoom no hauv cov poov xab, nqaij, mis nyuj, thiab zaub ntsuab. Nws muaj txiaj ntsig zoo li tshuaj; peb tuaj yeem siv cov tshuaj no los ntawm lub qhov ncauj los tiv thaiv thiab kho pellagra. Nicotinic acid lossis niacin tuaj yeem siv 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 peb lub cev, nws tuaj yeem ua rau mob siab. Ntxiv mus, raws li kev tshawb fawb kev tshawb fawb, koob tshuaj ib txwm muaj kev nyab xeeb rau kev siv thaum cev xeeb tub.
Daim duab 02: Cov Qauv Tshuaj ntawm Nicotinamide
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 Niacin thiab Nicotinamide yog dab tsi?
Niacin yog cov organic compound uas muaj cov tshuaj formula C6H5NO2 Nicotinamide yog ib qho amide chemical compound uas muaj pawg ua haujlwm –C(=O)NH2 Qhov sib txawv tseem ceeb ntawm niacin thiab nicotinamide yog tias niacin yog qhov tseem ceeb hauv kev kho cov roj cholesterol siab thaum nicotinamide pab tau rau kev kho mob. mob caj dab thiab pellagra.
TThe hauv qab infographic nthuav tawm qhov sib txawv ntawm niacin thiab nicotinamide hauv daim ntawv qhia rau ib sab ntawm kev sib piv.
Summary – Niacin vs Nicotinamide
Niacin thiab nicotinamide yog ob hom thiab cov txiaj ntsig ntawm vitamin B3 thaum Nicotinamide yog amide derivative ntawm niacin. Qhov sib txawv tseem ceeb ntawm niacin thiab nicotinamide yog tias niacin yog qhov tseem ceeb hauv kev kho cov roj cholesterol siab thaum nicotinamide pab tau rau kev kho mob caj dab thiab pellagra.
