Explain about Riboflavin

Aqueous solution shows a pronounced green-yellow fluorescence, which is maximal at a pH of about, 6-7 and disappears upon the addition of acids and alkalis. Riboflavin shows amphoteric reaction. The isoelectric point of riboflavin is around 6.0. The melting point is approximately 280-285°C. Riboflavin is inactivated by exposure to day light and  UV light. Irradiation  of an alkaline solution produces yellowish-green lumiflavin. In neutral or acidic solutions, the colourless lumichrome is formed along with varying amounts of lumiflavin.
