Question

On boiling the egg, what structural changes are taking place in the egg white?

• A. The colour of the egg changes from colourless to white
• B. $2^o$ and $3^o$ structures are destroyed but $1^o$ structure remains intact
• C. $1^o$ ,$2^o$ and $3^o$ structures of egg are destroyed
• D. A reversible change takes place which can be reversed by decreasing the temperature

Answer 1

The correct option is B $2^o$ and $3^o$ structures are destroyed but $1^o$ structure remains intact

The coagulation of egg white on boiling is a common example of denaturation. Due to denaturation, the secondary and tertiary structure are destroyed but primary structures remains intact.
