A hard-boiled egg is taken and separated into two parts: P and Q having different colours. The parts P and Q are mashed separately and water is added to obtain their suspensions. When an alkaline solution of copper sulphate is added to the suspension of P, the solution remains blue. On the other hand, when an alkaline copper sulphate solution is added to the suspension of Q, then a violet colour is produced.
Which nutrient is present in part Q which is not present in part P?
