Denaturation
Captions available
The idea
Denaturation is the loss of a protein's folded structure, caused by heat, extreme pH, or conditions that disrupt the bonds holding its shape.
In practice
Heating an egg white denatures its proteins, turning clear, folded proteins into an opaque, tangled solid that cannot refold.
Where people slip
Denaturation changes a protein's shape, not its sequence — the amino acid chain stays intact even as its structure collapses.
