Ingcaciso yeMveliso
I-Riboflavin yivithamini B. Ibandakanyeka kwiinkqubo ezininzi emzimbeni kwaye iyimfuneko ekukhuleni kweeseli eziqhelekileyo kunye nomsebenzi. I-Riboflavin isetyenziswa rhoqo ngokudibeneyo kunye nezinye iivithamini ze-B kwiimveliso eziyinkimbinkimbi ze-vitamin B. I-Vitamin B2 ekugqibeleni yahlukaniswa nabamhlophe beqanda ngo-1933 kwaye yaveliswa ngokwenziwa ngo-1935. Igama elithi riboflavine lamkelwa ngokusemthethweni kwi-1960; nangona eli gama lalisetyenziswa ngokubanzi ngaphambi koko. Ngo-1966, i-IUPAC yayitshintsha yaba yi-riboflavin, esetyenziswa ngokuxhaphakileyo namhlanje.I-Riboflavin idityaniswe zizo zonke izityalo eziluhlaza kunye neebhaktheriya ezininzi kunye nomngundo. Ngoko ke, i-riboflavin ifumaneka, ubuncinane ngamanani amancinci, kuninzi lokutya. Ukutya okuphakamileyo kwi-riboflavin ngokwemvelo kubandakanya ubisi kunye nezinye iimveliso zobisi, inyama, amaqanda, intlanzi enamafutha kunye nemifuno eluhlaza emnyama. I-Vitamin B2, njengesongezelelo sesondlo, isetyenziswa ngokubanzi kumgubo wengqolowa, iimveliso zobisi kunye nesosi. Ngamanye amaxesha isetyenziswa njenge pigment.
Iinzuzo zeRiboflavin
I-Riboflavin i-vitamin e-soluble efakwe kakuhle emanzini, enendima ebalulekileyo yokugcina impilo yabantu ngokubanzi. Idlala indima enkulu ekuveliseni amandla ngokuncedisa kwimetabolism yamafutha, iicarbohydrates, kunye neeproteni. I-Riboflavin ibalulekile ekwenziweni kweeseli ezibomvu zegazi ezintsha kunye nezilwa-buhlungu ebantwini, nto leyo eyandisa ukujikeleza kunye neoksijini kumalungu ahlukeneyo omzimba.
I-Riboflavin ibaluleke kakhulu ekuqinisekiseni ukukhula okufanelekileyo kunye nophuhliso lwamalungu okuzala, kunye nokukhula kwezicubu zomzimba ezifana nolusu, izicubu ezidibeneyo, amehlo, i-mucous membranes, inkqubo ye-nervous, kunye ne-immune system. Ukongeza, ikwaqinisekisa ulusu oluqhelekileyo, iinzipho kunye neenwele.
I-Riboflavin inokunceda ukukhusela iimeko ezininzi eziqhelekileyo ezifana nentloko ebuhlungu, i-cataract, i-acne, i-dermatitis, i-rheumatoid arthritis, kunye ne-eczema.
I-Riboflavin inokunceda ekunikezeni isiqabu kwiimpawu zeemeko ezahlukeneyo zenkqubo ye-nervous ezifana nokuba ndindisholo kunye nokuxhalaba phakathi kwabanye. Kucingelwa ukuba i-riboflavin, xa isetyenziswa kunye ne-vitamin B6, iyasebenza ekunyangeni iimpawu ezibuhlungu ze-carpal tunnel syndrome.
I-Riboflavin inxulunyaniswa nokuqulunqwa kweeprotheni, nto leyo eyenza iyimfuneko ekukhuleni okuqhelekileyo komzimba.
I-Riboflavin idlala indima enkulu ekuqinisekiseni ii-corneas eziqhelekileyo kunye nombono ogqibeleleyo. Inceda ekufunxeni kweeminerali ezifana nesinyithi, i-folic acid, kunye neevithamini ezongezelelweyo ezifana ne-B1, B3, kunye ne-B6. Ikwadlala indima ebalulekileyo ekulungiseni izicubu, ukuphiliswa kwamanxeba kunye nolunye ukwenzakala okunokuthatha ixesha elide ukuchacha ngokupheleleyo.
IRiboflavin ikwanceda ekomelezeni ukhuseleko lwendalo ngokomeleza amajoni omzimba kunye nokomeleza inkqubo yokuzikhusela kusulelo. Khumbula ukuba ube nokutya okunokulinganisela ukuqinisekisa ukubonelela nge-riboflavin, ekufuneka ihlaziywe yonke imihla.
Ukusetyenziswa kweKlinikhi
Ukunqongophala okukhulu kwe-riboflavin kwaziwa ngokuba yi-ariboflavinosis, kwaye unyango okanye uthintelo lwale meko kuphela kokusetyenziswa kwe-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, ii-pathologies ezinzima ngakumbi zikhula de kube sekufeni. Ukunqongophala kwe-Riboflavin kunokuvelisa iziphumo ze-teratogenic kunye nokuguqula ukuphathwa kwentsimbi ekhokelela kwi-anemia.
