I-Vitamin B2 (i-riboflavin) ikhiqizwa imvubelo evela ku-glucose, urea, nosawoti wamaminerali ekuvubeleni kwe-aerobic.
Isici somsoco esitholakala obisini, amaqanda, ibhali elibolile, isibindi, izinso, inhliziyo, imifino enamaqabunga.Umthombo wemvelo ocebile imvubelo.Amanani amaminithi akhona kuwo wonke amangqamuzana ezitshalo nawezilwane.I-Vitamin (i-enzyme cofactor).
Vitamin B2;I-Vitamin cofactor;I-LD50(igundane) 560 mg/kg ip.
i-riboflavin (i-Vitamin B2) isetshenziswa ekulungiseleleni ukunakekelwa kwesikhumba njenge-emollient.Ingatholakala emikhiqizweni yokunakekelwa kwelanga njengesithuthukisi se-suntan.Ngokwemithi, isetshenziselwa ukwelapha izilonda zesikhumba.
I-Riboflavin iyivithamini B2 encibilika emanzini edingekayo esikhumbeni esinempilo kanye nokwakhiwa nokugcinwa kwezicubu zomzimba.iyimpushana ecwebezelayo ephuzi kuya kokusawolintshi.isebenza njenge-coenzyme kanye nomthwali we-hydrogen.azinzile ekushiseni kodwa ingase incibilike futhi ilahleke emanzini okupheka.izinzile uma igcinwa.imithombo ihlanganisa imifino enamaqabunga, ushizi, amaqanda, nobisi.
Ukushoda okukhulu kwe-riboflavin kwaziwa ngokuthi i-ariboflavinosis, futhi ukwelashwa noma ukuvimbela lesi simo kuwukuphela kobufakazi be-riboflavin.I-Ariboflavinosis ivame ukuhlotshaniswa nokuntuleka kwamavithamini amaningi ngenxa yokudakwa emazweni athuthukile.Ngenxa yenani elikhulu lama-enzyme adinga i-riboflavin njenge-coenzyme, ukushoda kungaholela ezinhlobonhlobo zokungajwayelekile.Kubantu abadala i-seborrheicdermatitis, i-photophobia, i-peripheral neuropathy, i-anemia, izinguquko ze-andoropharyngeal ezihlanganisa i-angular stomatitis, i-glossitis, ne-cheilosis, ngokuvamile ziyizimpawu zokuqala zokuntuleka kwe-riboflavin. Ezinganeni, ukuyeka ukukhula kungase kwenzeke.Njengoba ukuntula kuqhubeka, i-pathologies enzima kakhulu ikhula kuze kube sekufeni.Ukushoda kwe-riboflavin kungase futhi kukhiqize imiphumela ye-teratogenic futhi kuguqule ukuphatha okusansimbi okuholela ku-anemia.
