Vitamine B2 (riboflavin) ikorwa n'umusemburo ukomoka kuri glucose, urea, n'umunyu wa minerval muri fermentation ya aerobic.
Intungamubiri ziboneka mu mata, amagi, sayiri yanduye, umwijima, impyiko, umutima, imboga zifite amababi.Inkomoko karemano ikungahaye ni umusemburo.Umubare w'iminota iboneka mu ngirabuzimafatizo zose.Vitamine (enzyme cofactor).
Vitamine B2;Cofactor ya Vitamine;LD50 (imbeba) 560 mg / kg ip.
riboflavin (Vitamine B2) ikoreshwa mu myiteguro yo kwita ku ruhu nka emollient.Irashobora kuboneka mubicuruzwa byita ku zuba nkuwongera suntan.Mubuvuzi, ikoreshwa mukuvura ibikomere byuruhu.
Riboflavin ni vitamine b2 ikenera amazi akenewe ku ruhu rwiza no kubaka no gufata neza umubiri.ni umuhondo kugeza orange-umuhondo w'ifu ya kristalline.ikora nka coenzyme nogutwara hydrogen.birahamye gushyuha ariko birashobora gushonga bikabura mumazi yo guteka.birasa neza kubika.inkomoko zirimo imboga zifite amababi, foromaje, amagi, n'amata.
Kubura cyane kwa riboflavin bizwi nka ariboflavinose, kandi kuvura cyangwa gukumira iyi ndwara nibyo byonyine byerekana riboflavin.Ariboflavinose ikunze guhuzwa no kubura vitamine nyinshi bitewe nubusinzi bwibihugu byateye imbere.Kubera ubwinshi bwimisemburo isaba riboflavin nka coenzyme, deficiencycan iganisha kumurongo udasanzwe.Ku bantu bakuze seborrheicdermatitis, Photophobia, neuropathie periferique, anemia, na andoropharyngeal impinduka zirimo angular stomatitis, glossitis, na cheilose, nibimenyetso byambere byerekana kubura kwa riboflavine.Mu bana, guhagarika gukura nabyo birashobora kubaho.Nkuko kubura gutera imbere, indwara zikomeye ziratera imbere kugeza apfuye.Kubura Riboflavin birashobora kandi kubyara teratogeniceffects no guhindura imikorere yicyuma iganisha ku kubura amaraso.
