Qhov sib txawv tseem ceeb ntawm nicotinamide thiab nicotinamide riboside yog nicotinamide yog ib qho aryl amide compound uas muaj -C(=O)NH2 ua haujlwm pab pawg thaum nicotinamide riboside yog cov tshuaj lom neeg ua los ntawm kev sib xyaw ntawm nicotinamide molecule nrog ribose qab zib. molecule.
Nicotinamide yog ib daim ntawv ntawm kev noj haus ntxiv uas peb tuaj yeem txiav txim siab ua ib daim ntawv ntawm vitamin B3. Nws tshwm sim hauv cov zaub mov, thiab peb kuj siv tau los ua tshuaj.
Nicotinamide yog dab tsi?
Nicotinamide yog ib qho tshuaj amide uas muaj pawg ua haujlwm -C(=O)NH2. Nws yog ib daim ntawv ntawm vitamin B3, thiab peb tuaj yeem pom qhov 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.
Daim duab 01: Cov Qauv Tshuaj ntawm Nicotinamide
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.
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. Tsis tas li ntawd, qhov sib xyaw no tuaj yeem raug hloov pauv cov tshuaj electrophilic thiab hloov pauv ntawm nws ob pawg ua haujlwm.
Nicotinamide Riboside yog dab tsi?
Nicotinamide ribose lossis NR yog pyridine-nucleoside muaj cov qauv zoo ib yam li cov vitamin B3. Cov tshuaj no tuaj yeem ua haujlwm ua ntej rau nicotinamide adenine dinucleotide lossis NAD +. Xyoo 1944, cov tshuaj no tau raug hu ua qhov kev loj hlob (npe hu ua Factor V), rau cov kab mob Haemophilus influenza. Cov kab mob no nyob thiab nyob ntawm cov ntshav.
Daim duab 02: Cov qauv tshuaj ntawm Nicotinamide Riboside
Thaum xav txog kev sib txuas ntawm nicotinamide riboside compound, muaj ntau txoj hauv kev biosynthetic. Lub enzyme hu ua "phosphoribosyltransferase" tuaj yeem ua rau kev hloov pauv ntawm nicotinamide rau hauv NAD + uas tuaj yeem hloov mus rau nicotinamide riboside txawm tias NR kinase enzyme.
Qhov txawv ntawm Nicotinamide thiab Nicotinamide Riboside yog dab tsi?
Nicotinamide thiab nicotinamide riboside yog ob hom amide sib txawv. Qhov sib txawv tseem ceeb ntawm nicotinamide thiab nicotinamide riboside yog nicotinamide yog ib qho amide compound uas muaj -C(=O)NH2 ua haujlwm pab pawg thaum nicotinamide riboside yog cov tshuaj lom neeg ua los ntawm kev sib xyaw ntawm nicotinamide molecule nrog ribose qab zib molecule. Ntxiv mus, nicotinamide yog siv los ua kev noj zaub mov ntxiv thiab ua tshuaj thaum nicotinamide riboside siv los ua tus thawj coj rau nicotinamide adenine dinucleotide lossis NAD +.
Cov hauv qab no infographic tabulates qhov sib txawv ntawm nicotinamide thiab nicotinamide riboside rau ib sab ntawm kev sib piv.
Summary – Nicotinamide vs Nicotinamide Riboside
Nicotinamide yog tshuaj, thiab nws yog ib daim ntawv ntawm vitamin B3. Nicotinamide riboside tuaj yeem tsim los ntawm nicotinamide los ntawm txoj kev biosynthesis nrog kev siv cov enzymes. Qhov sib txawv tseem ceeb ntawm nicotinamide thiab nicotinamide riboside yog tias nicotinamide yog ib qho amide compound uas muaj -C (=O) NH2 ua haujlwm pab pawg whereas nicotinamide riboside yog cov tshuaj lom neeg ua los ntawm kev sib xyaw ntawm nicotinamide molecule nrog ribose qab zib molecule.
