Question

What is isoelectric point in proteins?​

Answer 1

Explanation:

=> Isoelectric point is that point of PH at which amino acids have both positive and negative charge in a equal amount.

=> Isoelectric point is a specific value of PH at which amino acids move neither towards cathode nor towards anode.

Answer 2

Explanation:

In proteins the isoelectric point (pI) is defined as the pH at which a protein has no net charge.

When the pH > pI, a protein has a net negative charge and when the pH < pI, a protein has a net positive charge.
