| Target | IC50: chromogenic analytical probe[1] |
| In vitro | Ninhydrin (triketohydrindene hydrate) is used to assess amino acid qualitatively and quantitatively in ninhydrin reaction. All amino acids having α amino group, when heated in excess of ninhydrin give a purple coloured product. Only proline and hydroxyproline- amino acids molecules which contain a secondary amino group produce yellow condensation product. The colour intensity is proportional to the concentration of amino acid i.e. ammonia from the amino groups. |
