The reaction between alpha-amino acid and ninhydrin involved in the development of color are described by the following five mechanistic steps: alpha-amino acid + ninhydrin ---> reduced ninhydrin + alpha-amino acid + H2O alpha-amino acid + H2O ---> alpha-keto acid +NH3 alpha-keto acid + NH3 ---> aldehyde + CO2 Step (1) is an oxidative deamination reaction that removes two hydrogen from the alpha-amino acid to yield an alpha-imino acid. Simultaneously‚ the original ninhydrin is reduced
