Description:Yellow to orange yellow crystalline powder, has a variety of crystalline, micro-foul, with bitter taste. About **0℃ in the melting and decomposition. Specific rotation isï¼»aï¼½*0D: ***5 ° ***0 °. Saturated aqueous solution was neutral, yellow-green, with fluorescence, scattered light from the dry, but light in solution or lead to deterioration. Very stable under neutral or acidic. alkaline rapidly decomposed when light is faster decomposition, the formation is flavin-ray. More stable to oxidants, reducing the loss of the event and fluorescent yellow. Extremely difficult to dissolve in water, 1g dissolved in ***0 to about ****0ml water, due to crystalline form to another. Solubility in ethanol than in water and poor. Insoluble in ether and chloroform, but easily soluble in dilute alkali. In sodium hydroxide aqueous solution for the left. In hydrochloric acid aqueous solution for the right.

Application:
Riboflavin metabolism is component of many enzymes in the body, riboflavin is now found to contain more than **0 kinds of the enzyme, which the majority participation in the body\'s bio-oxidation and respiratory chain metabolism.
