Can you distinguish proteins and other amino compounds by the ninhyndrin test?
Because proteins are polymers of amino acids, hydrolysis followed by amino acids determination is a method. Ninhydrin is an oxidating agent which leads to the oxidative deamination of alpha-amino groups. Ninhyndrin test is used to detect ammonia, primary (deep blue or purple color (Ruhemann's purple)) and secondary amines (yellow), this is a proof of free amino acids in proteins. to distinguisn between Amino Acids and proteins you need a peptide bond test which can be done by Biuret test.
