Riboflavin /Vitamin B2 (83-88-5)
Sharaxaada Alaabta
Riboflavin, oo sidoo kale loo yaqaan fitamiin B2, waa fiitamiin laga helo cuntada waxaana loo iibiyaa kaab cunto ahaan.[3]Waxay lagama maarmaan u tahay sameynta laba koenzymes oo waaweyn, flavin mononucleotide iyo flavin adenine dinucleotide.Coenzymes-yadani waxay ku lug leeyihiin dheef-shiid kiimikaadka tamarta, neefsiga gacanta, iyo soosaarka antibody-ka, iyo sidoo kale korriinka iyo korriinka caadiga ah.Coenzymes-ka ayaa sidoo kale looga baahan yahay dheef-shiid kiimikaadka niacin, fitamiin B6, iyo folate.Riboflavin waxaa loo qoray in lagu daweeyo khafiifinta xudunta, oo afka laga qaato, waxay yarayn kartaa dhacdooyinka madax xanuunka dhanjafka ee dadka waaweyn.
Yaraanta Riboflavin waa dhif waxaana badanaa la socda yaraanta fiitamiinada iyo nafaqooyinka kale.Waxa laga yaabaa in lagaga hortago ama lagu daweeyo dawooyinka afka ama irbado.Fiitamiinada biyaha ku milma, riboflavin kasta oo la isticmaalo in ka badan baahida nafaqada lama kaydiyo;lama nuugo ama waa la nuugo oo si degdeg ah ayay kaadidu uga soo baxdaa, taasoo keenta in kaadidu yeelato midab huruud ah oo dhalaalaya.Ilaha dabiiciga ah ee riboflavin waxaa ka mid ah hilibka, kalluunka iyo shimbiraha, ukunta, waxyaabaha caanaha laga sameeyo, khudaarta cagaaran, boqoshaada, iyo yicibta.Wadamada qaar waxay u baahan yihiin ku darida badarka.
Hawlaha
Dheef-shiid kiimikaadka tamarta, neefsiga unugyada, soosaarka antibody-ka, koritaanka iyo horumarka.Riboflavin ayaa lagama maarmaan u ah dheef-shiid kiimikaadka karbohaydraytyada, borotiinka iyo dufanka.FAD waxay gacan ka geysataa beddelka tryptophan ilaa niacin (vitamin B3) iyo beddelka fitamiin B6 ee coenzyme pyridoxal 5' -phosphate waxay u baahan tahay FMN.Riboflavin wuxuu ku lug leeyahay ilaalinta heerarka wareegga wareegga caadiga ah ee homocysteine ;Yaraanta riboflavin, heerarka homocysteine ayaa kordha, taasoo kor u qaadeysa khatarta cudurada wadnaha.
