84. The physical property that allows mucins (mucus glycoproteins) to form thick, protective viscoelastic gels is their ability to

A. Dissolve completely into single atoms
B. Form extensive intermolecular disulfide bonds and trap water molecules
✓
C. Condense into solid crystalline structures inside the cell
D. Bind directly to the hydrophobic core of the nuclear membrane

📝 Explanation

Mucins cross-link via disulfide bonds to form large polymeric networks. Their hydrophilic sugar chains then trap water molecules to form a gel.

📖 Additional Information

  • Dissolve completely into single atoms
  • Form extensive intermolecular disulfide bonds and trap water molecules
  • Condense into solid crystalline structures inside the cell
  • Bind directly to the hydrophobic core of the nuclear membrane
