← ScienceWhich constraint occurs during polypeptide folding if hydrophobic residues cannot properly coalesce, impacting hydrogen bonds?
A)Impaired protein tertiary structure✓
B)Increased alpha helix formation
C)Accelerated disulfide bridge crosslinking
D)Enhanced hydrophilic residue exposure
💡 Explanation
Improper interactions prevent stabilizing hydrogen bonds, leading to impaired structures, because aggregation drives hydrophobic collapse. Without this collapse, key structure-stabilizing hydrogen bonds cannot form; therefore, tertiary structure integrity diminishes rather than other secondary structure enhancements.
