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

A Swiss chemist named Dr. Albert Hoffman first produced lysergic acid Diethylmide or best known as LSD in 1938 (Dye‚ 1992‚ p. 2). Hoffman discovered the drug while trying to synthesize a new drug for the treatment of headaches. He obtained the lysergic acid from the parasitic fungus that grows on rye plants known as ergot. From the lysergic acid‚ he synthesized the compound LSD. He used the compound to test for its pain killing properties on laboratory animals. Being that appeared totally ineffective

To determine if the reaction had gone to completion‚ a Starch/Iodine test was conducted. A change in the strip to a deep blue color would signal an excess of sodium hypochlorite reagent present. An excess is the reagent symbolizes the end of the reaction because there is no longer any reactant left to consume reagent. After the reaction was deemed completed‚ the product was isolated and purified by ether extraction‚ aqueous extraction and evaporation. To determine how sodium hypochlorite acts as
