Qauv
CovVitamin B2 (Riboflavin) 83-88-5 molecule yog tsim los ntawm heterocyclic isoalloxazine thiab riboflavin cawv. Riboflavin yog cov tshuaj fluorescent daj uas ruaj khov nyob rau hauv cov kua qaub thiab nruab nrab cov ntsiab lus tab sis yooj yim degraded nyob rau hauv alkaline ib puag ncig. Nyob rau hauv lub teeb pom kev, riboflavin yog tawg mus rau hauv photoflavin thiab photopigment.
Riboflavin cov ntaub ntawv
Nroj tsuag thiab kab mob tuaj yeem tsim riboflavin, tab sis tsiaj tsis tuaj yeem. Riboflavin feem ntau muaj nyob rau hauv pub, thiab tsiaj txhu tuaj yeem nqus tau los ntawm kev zom zaub mov ntawm cov tsiaj thiab cov nroj tsuag.
Riboflavin muaj ntau ntau hauv daim siab, ob lub raum, cov leeg, thiab cov khoom siv mis nyuj.
Tsaus ntsuab nplooj zaub muaj ntau riboflavin, thaum nplej muaj tsawg heev.
Vitamin B2 (Riboflavin) 83-88-5Hauv kev pub noj feem ntau yog tsim los ntawm flavin mononucleotide (FMN) thiab flavin adenine dinucleotide (FAD).
Kev nqus thiab thauj
plab hnyuv phosphatase hydrolyze flavin mononucleotide thiab flavin adenine dinucleotide nyob rau hauv cov khoom noj rau hauv dawb riboflavin, uas yog absorbed los ntawm plab hnyuv hlwb. Lub jejunum yog qhov chaw ntawm riboflavin digestion. Riboflavin yog digestible nyob rau hauv cov tsiaj pub ntau tshaj cov nroj tsuag.
Lub apical daim nyias nyias ntawm cov hnyuv muaj cov riboflavin cov cab kuj (RF-1 thiab RF-2), uas yog sodium ion dependent thiab me ntsis pH rhiab heev.
Cov kab mob hauv plab siv ATP-subordinate flavin kinase los hloov dua feem ntau ntawm kev noj riboflavin rau hauv flavin mononucleotide, uas tom qab ntawd hloov mus rau hauv flavin adenine dinucleotide.
Qhov seem dawb riboflavin nyob rau hauv cov hnyuv nkag mus rau lamina propria ntawm lub hauv paus membrane thiab ces nkag mus rau hauv cov hlab ntsha ntawm cov hlab ntsha. Riboflavin yog thauj los ntawm dawb los yog protein-binding (kwv yees li 50%), nrog nyob ib ncig ntawm 80% ntawm flavin mononucleotides (feem ntau yog los ntawm cell tawg) ua ke rau cov proteins. Cov proteins uas khi rau riboflavin thiab flavin mononucleotide hauv cov ntshav ntawm hydrogen bonds yog globulins thiab fibrinogen, feem ntau yog albumin.
Cov txiaj ntsig ntawm Riboflavin
Riboflavin yog ib qho tseem ceeb ntawm flavin mononucleotide thiab flavin adenine dinucleotide.
Flavin mononucleotide yog tsim los ntawm phosphorylation ntawm riboflavin, uas yuav tsum tau ATP. Flavin adenine dinucleotide synthase converts flavin mononucleotide thiab ATP rau hauv flavin adenine dinucleotide.
Cov txheej txheem no hloov AMP tivthaiv ntawm ATP rau hauv flavin mononucleotide. Flavin mononucleotide thiab flavin adenine dinucleotide yog oxidoreductase coenzymes lossis flavoproteins.
Cov ntawv cog lus tsis-covalent feem ntau yog siv los khi flavin mononucleotide thiab flavin adenine dinucleotide rau lawv cov khoom noj muaj protein ntau.
Flavoproteins muaj ib lossis ntau qhov tsim nyog hlau cofactors, li no lawv kuj hu ua hlau flavoproteins.
Kwv yees li 10% ntawm flavin adenine dinucleotide hauv hlwb yog covalently txuas rau enzymes xws li succinate dehydrogenase thiab monoamine oxidase.
Flavin proteases ceev cov txheej txheem metabolic uas ua rau tsim ntawm FMNH2 thiab FADH2. Flavin proteases ua haujlwm tseem ceeb hauv cov tsiaj metabolism xws li roj cholesterol, steroid synthesis, thiab vitamin D ntau lawm.
vitamin b2 deficiency
Tsiaj txhu uas muaj riboflavin tsis muaj peev xwm muaj kev noj qab haus huv tsis zoo, kev loj hlob qeeb, kev noj zaub mov qis dua, daim di ncauj chapped (kab ntawm lub ces kaum ntawm lub qhov ncauj), angular cheilitis (mob ntawm qhov ncauj mucosa), thiab kev ua haujlwm tsis zoo ntawm erythrocyte glutathione reductase.
Lwm cov tsos mob muaj xws li dermatitis, scrotal los yog vulvar pob, photophobia, neurological lesions, endocrine abnormalities, thiab anemia.
Kev tsis txaus riboflavin hnyav tuaj yeem ua rau muaj teeb meem loj hlob thiab kev loj hlob, dermatitis, thiab neurodegeneration.
Kuj ceeb tias, qhov tsis txaus ntawm riboflavin tsis cuam tshuam rau tus tsiaj txoj haujlwm metabolic.
Qhov kev piav qhia rau qhov no feem ntau yog tias riboflavin muaj zog sib koom ua ke rau cov protein hauv lub cev tsiaj, thiab kev hloov pauv qeeb heev, yog li depletion ntawm riboflavin hauv cov hlwb yuav siv sij hawm ntev.Cov ntaub ntawv no zoo li overly robotic.
Ntxiv rau cov tsos mob, cov tsiaj ua liaj ua teb uas tsis muaj riboflavin yuav pom cov tsos mob tshwj xeeb. Riboflavin deficiency nyob rau hauv npua ua rau tsis qab los noj mov, kev loj hlob retardation, ntuav, dermatitis, thiab ocular txawv txav. Noj zaub movVitamin B2 (Riboflavin) 83-88-5yog ib qho tseem ceeb ntawm cov noob qoob loo kom tswj tau cov kev ua estrus tsis tu ncua thiab zam kev ua haujlwm ntxov ntxov. Riboflavin deficiency nyob rau hauv me nyuam qaib impairs kev loj hlob thiab ua rau tuag tes tuag taw curled toes kab mob, uas yog txawv los ntawm sab hauv curving ntawm claws thiab tarsal taug kev, ib tug tsos mob tshwm sim los ntawm peripheral paj puas.
Riboflavin deficiency nyob rau hauv breeder hens impairs hatchability, ua rau embryo defects, thiab txawm ua rau ib tug tshwj xeeb club villus mob nyob rau hauv uas lub villus ntawm cov me nyuam qaib tseem loj hlob nyob rau hauv lub follicles, ua rau curled plaub. Ruminant rumen microbes tuaj yeem tsim cov riboflavin, yog li cov ruminants nrog cov rumen muaj nuj nqi tsis tshua muaj riboflavin insufficiency.
Calves thiab menyuam yaj tuaj yeem raug kev txom nyem los ntawm riboflavin deficiency, uas ua rau cov tsos mob xws li tsis qab los noj mov, raws plab, thiab daim di ncauj chapped.
Qyherb, ib tug ua manufacturers thiab lwm tus neegVitamin B2 (Riboflavin) 83-88-5nyob rau hauv Suav teb, yog renowned rau nws cov kev pab cuam thiab kev sis tw nqi. Yog tias koj xav tau kev lag luam wholesale, thov hu rau peb ntawminfo@dnbiology.com.
