I-Riboflavin / iVithamin B2(83-88-5)
Ingcaciso yeMveliso
I-Riboflavin, eyaziwa ngokuba yi-vitamin B2, yivithamin efumaneka ekutyeni kwaye ithengiswa njengesongezo sokutya.[3]Kubalulekile ekwenziweni kwee-coenzymes ezimbini eziphambili, i-flavin mononucleotide kunye ne-flavin adenine dinucleotide.Ezi coenzymes zibandakanyeka kwi-metabolism yamandla, ukuphefumla kweselula, kunye nokuveliswa kwe-antibody, kunye nokukhula okuqhelekileyo kunye nophuhliso.Iicoenzymes zikwafuneka kwimetabolism ye-niacin, ivithamin B6, kunye ne-folate.I-Riboflavin imiselwe ukuphatha i-corneal thinning, kwaye ithathwe ngomlomo, inokunciphisa iziganeko zentloko ye-migraine kubantu abadala.
Ukunqongophala kwe-Riboflavin kunqabile kwaye ngokuqhelekileyo kuhamba kunye nokusilela kwezinye iivithamini kunye nezondlo.Isenokuthintelwa okanye inyangwe ngezongezelelo zomlomo okanye ngeenaliti.Njengevithamini enyibilikayo emanzini, nayiphi na i-riboflavin esetyenzisiweyo ngaphezu kweemfuno zesondlo ayigcinwanga;mhlawumbi ayifuntshwa okanye ifunxwe kwaye ikhutshwe ngokukhawuleza kumchamo, ibangela ukuba umchamo ube ne-tint ephuzi ephuzi.Imithombo yendalo ye-riboflavin ibandakanya inyama, intlanzi kunye nentaka, amaqanda, iimveliso zobisi, imifuno eluhlaza, amakhowa kunye neealmond.Amanye amazwe afuna ukongezwa kwawo kwiinkozo.
Imisebenzi
amandla e-metabolism, ukuphefumla kweseli, ukuveliswa kwe-antibody, ukukhula kunye nophuhliso.I-Riboflavin ibalulekile kwi-metabolism ye-carbohydrates, iprotheni kunye namafutha.I-FAD igalelo ekuguquleni i-tryptophan kwi-niacin (i-vitamin B3) kunye nokuguqulwa kwe-vitamin B6 kwi-coenzyme pyridoxal 5 '. -iphosphate ifuna i-FMN.I-Riboflavin ibandakanyeka ekugcineni amanqanaba aqhelekileyo okujikeleza kwe-homocysteine;ekuswelekeni kwe-riboflavin, amanqanaba e-homocysteine ayanda, aphakamisa umngcipheko wezifo zentliziyo.
