When egg white is heated, it hardens and is opaque. This cooking process cannot be reversed, but hard-boiled egg white can be di
marshall27 [118]

Answer:

Generally proteins are denatured at high temperature.Therefore when  the egg is hard boiled they are denatured since eggs are protein,  the 3-dimensional  structure of protein is lost, and it is replaces with tangled meshwork of polypeptide chains .This is because the  orderly arrangements of  disulphide bonds in proteins  are disrupted , which  results in the formation of inter chains bonds among   disulphide bonds, making the protein molecules to link together.This explains the reason for the 3-D structure disruption  and formation of  a macro molecule.

However,   the  addition of reducing agent ,  breaks the covalent disulphide bonds.   While detergent breaks the interchain bonds among the disulphide bonds.  (The noncovalent bonds),These combined effects untangled the  mesh networks of polypeptides formed, and reduces the hardened nature,
