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。 |
| 产品介绍 | 带1分子结晶水。溶于醇；水，微溶于醚和氯仿。见光或露置空气中逐渐变色，能吸潮结块。100℃以上变为红色，240~245℃之间熔化分解。 |
| 生化机理 | Ninhydrin reacts with primary and secondary amines producing a blue or purple reaction product (diketohydrindylidene-diketohydrindamine). Ninhydrin is commonly used for the development of fingermarks on porous surfaces and is often used in comparison with other latent fingerprint techniques. Studies have indicated that Ninhydrin may be useful for detecting ninhydrin-reactive nitrogens in soil for forensic applications. Other studies have indicated that the color developed after reaction of Ninhydrin and amino acids can vary depending on the composition and type of amino acids. Additionally noted to be useful in the analysis of free amino groups in proteins, peptides and amino acids. Slightly soluble in ether or chloroform. |
