Antiparallel β-sheets have:
A) sheets that progress from N to C termini in the same direction.
B) usually all of their hydrophobic residues on one side of the sheet.
C) all hydrophobic residues.
D) all hydrophilic residues.
E) fibers that can be stretched or extended, but are not flexible.

Question

Quizplus · Accepted Answer

Antiparallel β-sheets often have their hydrophobic residues on one side of the sheet, allowing them to participate in the formation of a hydrophobic core in globular proteins, or to interface with other hydrophobic surfaces in protein-protein interactions. This arrangement is crucial for the structural stability and functional specificity of many proteins.
