Examples of 'ninhydrin test' in a sentence
Meaning of "ninhydrin test"
ninhydrin test - This phrase is specific to a chemical analysis procedure. The ninhydrin test is a method used to detect the presence of amino acids, peptides, or proteins in a sample by reacting it with the reagent ninhydrin. The resulting reaction produces a distinct color change, which can be observed and used to determine the presence or concentration of these organic compounds
