Question
Chapter 21, Problem 22A
Interpretation Introduction
Interpretation:
The effect of a permanent wave on structure of the protein must be explained. The amino acid that undergoes reaction during a permanent wave must be explained. The level of structure for the hair protein which gets affected needs to be explained.
Concept Introduction:
“Permanent wave” is a process in which hair shape can be changed to desired shape with the help of chemicals and heat.
Expert Solution & Answer
Answer to Problem 22A
“Permanent wave” can change the structure of a protein by reduction and oxidation process.
Cysteine undergoes reaction during a permanent wave.
Tertiary structure of protein is affected during a “Permanent wave”.
Explanation of Solution
Natural disulfide (S-S) bonds in protein are broken first by reduction process in which free thiol groups (SH) are generated. Then hair I given desired shape by altering the tertiary structure due to chain shifting of protein. Finally to stabilize the new tertiary structure a final oxidation is performed in which new cysteine linkages (S-S) are formed.
The process is explained as follows:
