|Section2= |Section3= }} 2,6-Dihydroxypyridine is an alkaloid with the molecular formula C5H3N(OH)2. It is a colorless solid. 2,6-Dihyroxypyridine is an intermediate in the degradation of nicotine. == Preparation == 2,6-Dihydroxypyridine is an intermediate in the degradation of nicotine by the aerobic bacterium ''Arthrobacter nicotinovorans''. The following reaction shows the formation of the intermediate from L-nicotine of tobacco. :500px The figure represents the pathway for the degradation of L-nicotine by ''A. nicotinovorans'' to 2,6-dihydroxypyridine Another reaction of 2,6-dihydroxypyridine highlights its function as a substrate for oxygenase. One example is the enzyme monooxygenase, which oxidizes the substrate by transferring one oxygen atom of O2 to the substrate. The other oxygen atom is reduced to water. The product of the oxidase reaction was determined to be 2,3,6-tri-hydroxypyridine because of the results of the stoichiometry as well as the results of the ultraviolet spectrum. This reaction can be shown by the following equation: :400px Arthrobacter oxydans, when grown on agar plates, were most active in the oxidation of 2,6-dihydroxypyridine. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「2,6-Dihydroxypyridine」の詳細全文を読む スポンサード リンク
