what is ninhydrin reaction?how it is useful?..

Answer / akhila

this is a reaction of aminoacid with triketohydrindene
hydrate;
ninhydrin=indane-1,2,3-trione hydrate
it is a powerful oxidising agent and causes oxidative
decarboxylation of alpha aminoacids producing co2 ,nh3 and
an aldehyde with one less carbon atom than the parent amino
acid.
the reduced ninhydrin reacts with the liberated nh3 and a
mole of ninhydrin forming blue coloured ruheman's complex.
this is known as ninhydrin reaction.
