Study notes
Why does boiling an egg permanently change it? Step 1: Egg white = albumin protein (folded, soluble, transparent). Step 2: Heat breaks H-bonds/hydrophobic interactions holding the 3D shape. Step 3: Protein unfolds (denatures) → chains tangle → white, solid, opaque. Step 4: Denaturation is irreversible here — the native fold can't reform. Structure = function!
