  • 茚三酮反应(和氨基酸的反应):茚三酮反应(ninhydrin reaction)这是氨基酸的α-NH2所引起的反应。α-氨基酸与水合茚三酮一起在水溶液中加热,可发生反应生成蓝紫色物质。首先是氨基酸被氧化分解,放出氨和二氧化碳,氨基酸生成醛,水合茚三酮则生成还原型茚三酮。在弱酸性溶液中,还原型茚三酮、氨和另一分子茚三酮反应,缩合生成蓝紫色物质。 所有氨基酸及具有游离α-氨基的肽都产生蓝紫色,但脯氨酸和羟脯氨酸与茚三酮反应产生黄色物质,因其α-氨基被取代,所以产生不同的衍生物。此反应十分灵敏,根据反应所生成的蓝紫色的深浅,在570nm波长下进行比色就可测定样品中氨基酸的含量。也可在分离氨基酸时作为显色剂定性、定量地测定氨基酸。

  • 茚三酮:茚三酮又名“茚满三酮”、“水合茚三酮”、“宁海群”。检测α-氨基酸与多肽常用的显色剂。白色柱晶,在125℃或放置过久变红,239~240℃分解,微溶于水,易溶于丙酮、丁醇等有机溶剂。在溶液中遇α-氨基酸,或任何含α-氨基物质能形成深蓝色乃至粉红或红色物质,故常用作朊类降解物和α-氨基化合物试剂。此项反应又叫“茚三酮反应”。 茚三酮结构式 茚三酮是一种用来检测蛋白质和氨基酸存在与否的试剂。当溶液中存在α氨基酸时,它的水溶液变蓝。将茚三酮溶解在有机溶剂中,它可作为氨基酸层析时的显影剂。若对茚三酮处理的层析图剧烈加热,则氨基酸显示为紫色斑点,可用来测定Rf值。茚三酮是致癌剂。 以上信息由Chemicalbook的彤彤编辑整理。
  • 用途三:该品是蛋白质、氨基酸及蛋白胨的灵敏显色试剂。〔水合〕茚三酮 ninhydrin 为茚三酮的水合物。是灵敏的氨基酸显色试剂。α-氨基酸与水合茚三酮一起加热显蓝紫色(脯氨酸和羟脯氨酸显黄色),称此为水合茚三酮反应。此反应应用于纸层析及滤纸电泳的氨基酸和肽的测定,以及氨基酸自动定量分析等。
