IVithamin B2 (i-riboflavin) iveliswa yigwele kwiglucose, urea, kunye neetyuwa zeminerali kwi-fermentation ye-aerobic.
Isondlo esifumaneka kubisi, amaqanda, ibhali ebolile, isibindi, izintso, intliziyo, imifuno enamagqabi.Umthombo ocebileyo wendalo yigwele.Izixa zomzuzu ezikhoyo kuzo zonke iiseli zezityalo kunye nezilwanyana.I-Vitamin (i-enzyme cofactor).
iVithamini B2;I-Vitamin cofactor;LD50(impuku) 560 mg/kg ip.
i-riboflavin (i-Vitamin B2) isetyenziswa kumalungiselelo okunyamekela ulusu njenge-emollient.Inokufumaneka kwiimveliso zokunakekelwa kwelanga njenge-suntan enhancer.Amayeza, isetyenziselwa unyango lwezilonda zesikhumba.
I-Riboflavin yi-vitamin B2 enyibilikayo emanzini efunekayo elusu olusempilweni kunye nokwakhiwa kunye nokugcinwa kwezicubu zomzimba.ngumgubo wekristale otyheli ukuya kwe-orenji-tyheli.isebenza njenge-coenzyme kunye nomphathi we-hydrogen.iyazinzile ekutshiseni kodwa inokunyibilika kwaye ilahleke emanzini okupheka.izinzile kugcino.imithombo iquka imifuno enamagqabi, itshizi, amaqanda, nobisi.
Ukunqongophala okukhulu kwe-riboflavin kwaziwa ngokuba yi-ariboflavinosis, kwaye unyango okanye uthintelo lwale meko kuphela kobungqina be-riboflavin.I-Ariboflavinosis idla ngokunxulunyaniswa nokunqongophala kweevithamin ezininzi ngenxa yokusela utywala kumazwe athuthukileyo.Ngenxa yenani elikhulu lee-enzymes ezifuna i-riboflavin njenge-coenzyme, ukusilela kunokukhokelela kuluhlu olubanzi lwezinto ezingaqhelekanga.Kubantu abadala i-seborrheicdermatitis, i-photophobia, i-peripheral neuropathy, i-anemia, utshintsho lwe-andoropharyngeal kuquka i-angular stomatitis, i-glossitis, kunye ne-cheilosis, zihlala ziyimpawu zokuqala zokunqongophala kwe-riboflavin.Njengoko ukusilela kuqhubela phambili, iipathologies eziqatha ngakumbi zikhula de kufe.Ukunqongophala kweRiboflavin kunokuvelisa iziphumo ze-teratogenic kunye nokuguqula ukuphathwa kwentsimbi ekhokelela kwi-anemia.
