1 [生化]?茚三酮反应 ...n):在一定的条件下,变性的生物...胺基或巯基之间缩合形成的缩醛或缩酮键,常见的糖醛... 回复: 5,茚三酮反应(ninhydrin reaction):在加热条件下,.. 2 ?茚三酮反映 ⒈茚三酮反映(ninhydrin reaction)：卵白质经水解后孕育发生的氨基酸也可发生茚三酮反映。 3 ?酮反响 5，茚三酮反响（ninhydrin reaction）：正在加热条件下，氨基酸或肽与茚三酮反响天生紫色（与脯氨酸反响天生）化合物的反响。
- 1
Its ninhydrin reaction was negative, but after acid hydrolysis, its ninhydrin reaction and biuret reaction were positive. 茚三酮反应呈阴性，用酸水解后茚三酮反应和双缩脲反应呈阳性。 - 2
Methods: color reaction of free amino acids with ninhydrin was adopted, since, in certain extent, the color depth is correlated with the amino acid content. 方法：采用氨基酸的游离氨基与水合茚三酮产生显色反应，在一定范围内，其颜色的深浅与氨基酸的含量成正比。 - 3
The surface amino group was transferred to the aldehyde group after it reacted with ninhydrin. The surface aldehyde group was confirmed by the mirror reaction. 表面的伯胺基在与茚三酮反应后转化为醛基，通过银镜反应证明了醛基的存在。
