Vitamine B2 (Riboflavin) |83-88-5

Vitamine B2, izwi kandi ku izina rya riboflavin, irashobora gushonga gato mu mazi, igahinduka mu muti utabogamye cyangwa acide munsi yo gushyuha.Nibigize cofactor ya enzyme yumuhondo ishinzwe gutanga hydrogen muri redox biologique mumubiri.

Iriburiro ryibicuruzwa Iki gicuruzwa nigikoresho cyumye cyumubyimba wakozwe na fermentation ya mikorobe aho ikoresha glucose ya sirupe hamwe numusemburo wumusemburo nkibikoresho fatizo, hanyuma bigatunganywa binyuze mu kuyungurura membrane, korohereza, hamwe no kumisha.

Ibyiza byumubiri Iki gicuruzwa kigomba kongerwaho ibiryo byamatungo hagamijwe kubungabunga ubuzima bwumubiri, kwihuta gukura no gutera imbere, no gukomeza ubusugire bwuruhu nuruhu.Igicuruzwa ni umuhondo kugeza umukara uringaniye cyane hamwe ningingo ya 275-282 ℃, umunuko muke kandi usharira, ushonga mumuti wa alkali, udashonga mumazi na Ethanol. Riboflavin yumye ikomeza guhagarara neza kurwanya okiside, aside nubushyuhe ariko ntabwo ari alkali n'umucyo byatera kubora byihuse, cyane cyane mubisubizo bya alkaline cyangwa ultraviolet.Niyo mpamvu, birasabwa cyane ko iki gicuruzwa kigomba gufungwa kumucyo no kwirinda ibintu bya alkaline muri primaire kugirango gikemure igihombo kidakenewe, byongeye kandi mugihe hari amazi yubusa hafi --- amazi yubusa, nigihombo kinini.Ariko, Riboflavin ifite ituze ryiza niba bigaragara ifu yumye mu mwijima.Nyamara, kugaburira ibiryo hamwe no kubyara bigira ingaruka mbi kuri Riboflavin-- igipimo cya 5% kugeza 15% byigihombo ukoresheje pelleting na 0 kugeza kuri 25% muburyo bwo guhunika.
