Which one of the following reagents is used for identification of amino acids?
Correct answer: C. Ninhydrin
- A. Fehling's solution
- B. Benedict's solution
- C. Ninhydrin
- D. Copper (II) Sulphate
Explanation
The reagent used for the identification of amino acids is Ninhydrin.Ninhydrin is a chemical compound that reacts with amino acids to produce a colored compound. This reaction is known as the Ninhydrin test. When amino acids are treated with Ninhydrin, they form colored complexes, with different amino acids producing different colors. This property makes Ninhydrin a useful reagent for the detection and identification of amino acids in various chemical and biological samples.

About Macromolecules
Proteins are classified by shape, composition and structure, from primary amino acid sequence to secondary, tertiary and quaternary organisation, and their biological roles are linked to this structure. Enzymes are examined as protein biocatalysts, including active sites, substrate specificity, activation energy, cofactors and factors affecting activity.
