✦ Synopsis

Polarographic studies on the copper-threonine complex in alkaline medium

Copper(II) forms a violet complex with proteins in alkaline medium. The reaction, known as the"biuret test", has been used for about a century for the qualitative and quantitative determination of proteins 1. The reaction has been mostly studied by spectrophotometric methods but the polarographic method was found especially suitable for the study of the violet complexes formed by the interaction of copper(II) with certain amides, amino acids and related compounds 2-~. The present communication deals with the polarographic studies on the copper(II t-threonine complex in alkaline medium.
