Vhitamini B2 inobata mukukura kwemasero, inokurudzira kupora kwemaronda, inosimbisa nzara nebvudzi, uye zvakare chikamu chakakosha che coenzymes. Inobatanidzwa mukugadzirwa uye metabolism ye carbon Chemicalbook water compounds, mapuroteni nemafuta zvinovaka muviri, uye inobata mukugadzirwa kwemasero matsvuku eropa uye kutakurwa kwesimbi, izvo zvinobatsira kudzivirira. Inorapa anemia yekushaikwa kwesimbi uye inewo imwe mhedzisiro yekuderedza BP.
Hunhu hwemakemikari
Upfu hwekristaro hweyero kusvika kuorenji-yero, hunonhuwa zvishoma uye hunovava zvishoma. Nzvimbo yekunyunguduka 280℃ (kuora). Inonyunguduka nyore nyore mualkaline solution uye sodium chloride solution, inonyunguduka zvishoma mumvura, inonyunguduka zvishoma muethanol.Mvura inobuda mumvura ine yero-girini, uye mvura inobuda mumvura ine saturated haina kwayakarerekera. Inodzivirira kupisa zvakanaka uye inodzivirira acid. Inokuvara zviri nyore mualkaline solution kana kuti inosvibirwa nemwaranzi ye ultraviolet, uye haina kugadzikana kune zvinoderedza kupisa.
Basa remuviri uye mhedzisiro
Vhitamini B2 (riboflavin) ivhitamini inonyungudika mumvura, iri nyore kugaya nekupinza. Huwandu hunobuda hunowedzera kana kuderera zvichienderana nezvinodiwa nemuviri uye hunogona kunge huchienderana nekurasikirwa kwemapuroteni; haiunganidzike mumuviri, saka inowanzowedzerwa nechikafu kana zvekudya zvinovaka muviri. Kusiyana nevhitamini B1, vhitamini B2 inodzivirira kupisa, inodzivirira acid uye inodzivirira oxidation. Mukurapa, mapiritsi evhitamini B2 anoshandiswa kudzivirira nekurapa kushomeka kwevhitamini B2..
