"Ninhydrin" Meaning

Ninhydrin is a chemical reagent used in forensic science and genetics to detect and visualize the presence of amino acids, particularly the amino acid sequence of proteins. It works by reacting with the primary amino groups (-NH2) of amino acids to form a purple-colored compound called Ruhemann's purple. This reaction is commonly used in fingerprinting and DNA analysis to reveal the presence of proteins and amino acids on surfaces.
