Answer:

Step-by-step explanation:

This is because alkaline CuSO₄ reacts with compounds containing two or more peptide bonds to give a purple colored productwhich is due to formation of co-ordination complex of copper(II) ions with un-shared electron pairs of peptide nitrogen atoms and oxygen atoms of water.
