Draw the structure of a salt bridge between two keratin protein strands. What kinds of ions become common in high-pH solutions? Would these damage the salt bridge?

Interpretation Introduction

Interpretation:

The structure of a salt bridge is to be drawn, the ions that become common in high-pH solutions are to be predicted and whether these ions damage the salt bridge or not is to be explained.

Concept Introduction:

Hair contains a protein known as keratin. It contains NH3+ in the salt bridge.

Keratin contains three types of bridges, which are hydrogen bonds, salt bridges and disulfide bridges.

Explanation of Solution

Hair contains a protein known as keratin. Keratin contains three bridges: hydrogen bonds, salt bridges and disulfide bridges. A salt bridge is made up of two oppositely charge entities such as COO and NH3+.

The structure of the salt bridge between two keratin proteins is shown as follows:

Since, NH3+ makes keratin stronger, in highly basic medium, the concentration of
